Yes, you definately want to use LVM on top of the hardware raid you have
from the card (it'll present itself as a single scsi drive to the OS).
It'll give you the flexibility you might want in the future to do
basically anything, otherwise you're locked into what the 3ware can do for
you. It's really hard to do partitions on top of raid (due to the fact
that there is a 2TB limit on most standard partitioning schemes), LVM
solves that problem as well.
Also, I would really suggest you buy a third drive and go for raid5
directly if the 3ware card can't convert between raid0 and raid5.
