No. Rock Band 2 is more user friendly with better game play options and you can download all but 3 songs from rock band 1 to your hard drive to play in Rock Band 2 for around $5. (You will have to rent or borrow Rock band 1 disk to do this....but it doesn't take long and you must have a live account and access on the 360. I can only speak to this system.....not sure for other gaming systems.
No. Rock Band 1 doesn't have the option of cymbals.
Yes you can use The rock Band 2 set with Band hero. The Band Hero (Guitar Hero) Drum set has the Orange cymbal, which is one more pad than the rock Band 2 drum set. Fortunately Band Hero Detects that and modifies it songs for the Rock Band 2 Drum Set.
