The short of it: Backup your Wii games, backup your DS games if you're so inclined, using custom servers on Wii will require homebrew, and using custom servers on DS might only be possible with flash carts.

That means having to restart you Pokémon game, having to unlock every character again in Mario Kart or Brawl and other annoying things you'll have to do which aren't simply playing the game.
If I'm understanding things correctly, you won't have to worry much about DS games and their FCs. With Wii games
the only real way to get a new FC (which is what you'd need if you don't do this) is to delete your profile/data and start again. But with DS games, getting a new FC is almost trivial--just pop the game into a different DS, connect to Wi-Fi, and after some
complaining explaining that connecting will cause you to lose your current WFC ID and get a new one, you'll get a new FC. Pop that game back into your main DS, connect, and you'll get another new FC.
Anyone who shuffles DSs and plays Pokemon online can tell you about the odd times their FC randomly changed and they lost all their Pal Pad friends--this is exactly the thing that's happening, and losing your Pal Pad entries and getting a new FC is basically the extent of the harm suffered by doing this (if you do this in games like Picross DS, where you upload levels to the Internet for others to download, you will apparently lose access to those levels if you don't have them saved on your cart, but I think that's basically the worst effect).
If you don't have two DSs to do this with, I'm pretty sure going into the Wi-Fi settings and deleting your WFC ID will cause you to get a new one. Obviously, doing that will affect the WFC stuff in
all your games, but that shouldn't be too big of a problem.
HOWEVER: If you're in the unlikely situation of having ONLY a 3DS, having the very few DS games that CAN connect to WPA encrypted access points, and having NO way to change your router settings to use WEP or no encryption, then yes, you should probably back up your stuff, which is probably limited to the 5th Gen games and DSiWare. DSiWare is a bit more restrictive than normal DS games in that they're linked to your console, so you should back those up if you can't change your Wi-Fi from WPA to WEP/None down the road.
This just in, there is now a
utility to upload your MK Wii data to the custom servers after the shutdown.
This probably isn't as relevant for Brawl (because, honestly, who's still going to play that once SSB4 comes out) and Mario Kart Wii (although it might still be unique enough to warrant the occasional game even when MK8 comes out), but for your old Pokémon games, your own Animal Crossing villages and stuff like that this might be important. If anything, it's a zero-risk high-reward kind of proposition.
Well, they were motivated enough to do this for Mario Kart.
The analogue on handhelds for the Mario Kart situation would be MK DS to MK 7; DS has different tracks and a few quirks (can't hold items behind you; can only use certain items; these were limitations of the DS/early Wi-Fi, but I suppose they actually provide a different ruleset), but MK7 definitely replaced MK DS for most people. MK8 will, well, also replace MK Wii for most people, but MK Wii is in the unique situation of having
unauthorized user-generated content in the form of tracks and modes.
CTGP Revolution is a popular way to play these (many) tracks and (well, like, one) modes
online, and is sort of why the community started developing alternate servers (however the crap they did that, seriously, blows my mind). So yeah, move to MK8, and you lose all that work. :X
An important note is that you apparently need not only your own FC but the FC of someone who has you added, so get your friends to register as well. (On that note, bacon, PMJ, anyone else who has me added on MKW or SSBB, I'm in there.)
True, you need to have a friend registered for this to work, but you only need to register your own FC (
comments from the video uploader about this).
If anyone has any more details on how and why this will work, feel free to share. I don't have the time to do much research at the moment, but I figured I'd best get the word out as soon as possible, because the deadline is approaching rapidly.
Good luck!
How this will work: Using custom servers is going to require a few things. All Nintendo WFC games connect to servers encrypted with HTTPS. You need to get around that in order to use custom servers, which basically amounts to hacking the game:
For Wii games: The basic requirement is that you have homebrew installed. Homebrew utilities will allow you to patch the games so that you can use custom servers. In Mario Kart Wii's case, you'll be able to get the patch through CTGP Revolution, or through separate utilities.
For DS games: This gets a bit trickier, as the limited DS homebrew scene relies on you having a flash cart. Basically, the only way to patch these games is by patching the ROMs themselves with "No HTTPS" patches... and the only way to play those patched ROMs on a DS is with a flashcart. I might be wrong about this, but this is what I gleamed from the various Wii-Homebrew.com threads.
Why this will work: I don't know how the custom servers are actually working, but this import-Friend-Code-through-form thing will work because there's apparently a way to connect to Nintendo's servers and download the information of a user's friends. So following the 18th, when they actually set about downloading all this data, they'll look up your Friend Codes, see that you have friends, go to those friends, see that they're friends with you, and get the information from that, or something.
Other notes:
Finding Game IDs: Entering Friend Codes in the form requires you to know the game's Game ID. They have a list of popular games and their IDs on the form site, so look there first for your game. If you can't find it there, they link to
GameTDB, which lets you search for some games and find their IDs. If you can't find your needed ID
there:
Wii games: If you look at the disc, you'll see a number at the bottom. "RVL - XXXX - USA" | RVL is short for Revolution, the Wii's codename. USA obviously shows that the disc was for sale in the US (I think). You're interested in the XXXX, which will be the actual Game ID.
DS games: Similar situation. The number is at the bottom of the cartridge label, and instead of "RVL", it's "NTR", short for Nitro.
DSiWare games: The number is at the end of the in-game instruction manual. Just load up the game, look for "Instructions" or "Help", and go from there.
WiiWare games: Not sure about this one, but I think you can just check the Operations Manual. Get there by booting the game, pressing Home, and selecting "Operations", or if it's not there, check the Wii Shop entry.
If you add a Game ID that isn't registered in this database, you can add its name in the bottom form. Note, the ID needs to actually be in the database before you can add names.
Note about Game IDs and region: MrBean mentions using the correct letter for your region for the last digit of your MK Wii Game ID, but this isn't required--no matter what letter you put, everything is registered under XXXJ. So don't fret if you get that part wrong.

Note about getting "Some Inputs were not correct. Please recheck them.": Some games, especially DS games, seem to plumb not work when you register them. With DS games I'd say this doesn't matter much (see above), but if you can't register a Wii game, you might want to report it in the people's thread: "If something is not working as it should do, please report it here:
