Redundancy is always good! Some applications do not take full advantage of multi-processor servers. I am thinking the memory and the SCSI drives/controller card will definitely improve performance. If you use RAID 5 you'll have approx 16 GB of usable space. If you use disk striping (RAID 0) you may get better I/O performance but you lose any redundancy due to the fact that you will not be writing any parity to disk. If the price is right, go for it.
