No, they are two different games and software.
No, the Rock Band Stratocaster will work with World Tour, Rock Band 2, Aerosmith, and Rock Band only. It will not work with Guitar Hero II or Guitar Hero III.

Yes. But, I believe it has to be a next-generation console (Ps3/360).
Yes, the Kramer Striker works for; Guitar Hero I & II Guitar Hero Encore Guitar Hero III & World Tour Rock Band And maybe Aerosmith

You can play Rock band with a guitar hero guitar, but you can't play Guitar Hero with a Rock Band guitar.
You can use the Rock Band Guitars for GH : Smash Hits, GH: World Tour, Guitar Hero 5, and Band Hero. You have some issues with GH 3: Legends of Rock, Guitar Hero: Aerosmith. Any other GH games I have not tried personally
I dont believe so. I have a aerosmith from the guitar hero series it works for rock band but i dont think the rock band guitars work for guitar hero.
It depends on the console and which games. From my experience ( PS3) the rock band 2 Guitar work on guitar Hero games ( Aerosmith, smash hits, World Tour, GH 5, Band Hero) with the exception of Guitar Hero 3 : Legends of Rock. Other consoles vary, so this is the best answer i can give you
