you want a standard size sd card, not a micro sd card
also, that is way too big for the wii to read
this one should work fine, though I haven't tested it specifically
also, it's a hell of a lot cheaper than the one you linked :)
there is also a way to get wiimfi without an sd card, but wiimfi only allows you to play online (it doesn't have the features of ctgp, it just patches in an online server), and this process takes a few minutes every time you want to play
