No
when rock band 2 and guitar hero 4 come out, anyone who has rock band for any system EXCEPT wii will be able to use their rock band stuff for guitar hero, but u can't use guitarhero controllers for rock band

Yes, you need a guitar hero wireless control, or a guitar hero USB microphone, or guitar hero drumset. You cannot play with the wii remote alone.

no
