hi, i just modded my wii ver 3.3u with wiikey 2 sadly it is still region blocked, thats why i wanted to softmod it i was wodering if it was possible to install homebrew with the wiikey 2 inside the wii?

I'm no expert, but I think so

Yes

Now i have 3.3u would i still need the twilight hack for the homebrew to be installed in my wii? i already bought a 2gb SD card :D

You could use the twilight hack or bannerbomb.

once you have homebrew channel installed, use Gecko OS for region free.
