having second thoughts about the Wii Shop and IOS51 install

it seems like a harmless 3rd party update, but i have a few questions.

will it be removable? i need to know that if anything goes wrong if i can delete the patch cause some features on my wii arent worth risking

will this patch allow me to use the in-game store in guitar hero world tour? some people got the game for the wii early and i wanna know

yes it is removeable i think cuz ur can re - install it

"NOTE: TAKE OUT ANY GAMECUBE MEMORY CARDS/CONTROLLERS AND USB DEVICES BEFORE INSTALLING ANYTHING. The first time one person installed the IOS51, and Shop Channel. One person had a Gamecube memory card, and a wireless adapter in the Wii, and it didn’t install correctly. But after taking out all Gamecube items, re-installed everything and it worked fine. Axelpaxel was the one that found that USB devices did it too."

I don't know if you can use in game stare games i think u can

well even without the update i can go to the guitar hero store, but once some jerk i know gives me my 2000 wii points i will use the 3rd party update so i can go to the homebrew channel
