Nice avatar corkyg and nice answer!
The RAID array is seen by any good defrag program as a single lettered drive. No different. It may take a wee bit longer, but that's all.
This is by far the most coherent answer i have ever seen you post
Vista and Win7 both defrag on their own during idle time so it's not something you should care about. If you're running XP you should fix that before anything else.

No.
Depends on RAID type and/or controller. Crappy controller/software RAID = all drives may be visible, not the RAID unit.
Good controller (True RAID) = only the unit is presented to the OS.
