a) yes, although i believe when using raid0 the master boot table is not included in the mirror stripe.

b) a parity partition is located on each raid 5 drive, allowing to be recovered from n-1 (n = amount of drives) drives

c) depends on your hardware, easiest is replace the faulty drive and start up, it recovers automatically


raid 5 is quicker that raid 1 reading, slower when writing - usually.
if your using 3x74 disks then u will have (n-1)74 GB = 148GB
