in the wii shop

You can't. You have to buy them off the store, they are 250 Wii points each.
play songs, play games, and do tutorials
No theirs different songs on the wii version.
Buy a Wii Points card, or buy points directly from the Wii Store with a credit card, then use them to buy the songs currently for sale in the Guitar Hero store. I believe there is Metallica, Boston, Rick Springfield, and Blind Melon, among others. More will be added as time goes on.
