You will have one vg for the physical storage and then split
it into lv's for the mount points. The only reason for multiple
vg's is multiple storage systems (e.g., storage blocks on an
EMC or a standalone Storage Works unit) next to your machine.

None whatsoever. vg's group pv's together; partition the
space with lv's.
