I know the guitars do, but I'm pretty sure the drums don't work. :)
Rock Band games on PS2 only support PS2-style guitars and PS2/3 Rock Band guitars and drum kits. Guitar Hero: Aerosmith and newer on PS2 support all instruments from all consoles that the games have note charts for (so no drums on GH:Aerosmith but 360 and PS3 drums work on all full-band GH games).
Yes, you can. You can also play rock band with guitar hero guitars.
Yes, all rock band instruments work on every rock band game
Guitar+vocals+bass+drums=rock/metal band. Keyboard, extra guitars optional.

A rock band will generally contain the key board, one or two guitars and a drum-kit.
the ps2 kramer (GH3) and the guitar hero 1&2 guitars work for ps2 rock band games
