Guitar Hero Guitar Help

I bought Guitar Hero Aerosmith, World Tour, And Guitar Hero Legends of Rock for PS3 as a gift for Christmas however they did not have the guitars, drums, or mic. I have no experience with these so i am needing help on Which Guitars, drums or mic will work. It doesnt need to be new i dont mind getting it from ebay or amazon i just want to make sure it works! please provide a link if posssible.

Thanks for your help
