You will need both 32-bit and 64-bit drivers for every device on your
system.

32-bit software will run in an emulation layer when running on a 64-bit
system, so I doubt you will see performance increases. Same to decreased
performance is the most likely outcome.

Can't answer your other questions - check out the models of cards you're
interested in and see if they offer Vista drivers or not.
