I'd have thought "vgrename" would be sufficient - there shouldn't be any
need to rename the LVs once the VG is renamed.
If you do do this, check that /etc/fstab contains LABEL= lines to
identify mount points rather than hardcoded device names
like /dev/mapper/VolGroup00-LogVol00 or /dev/VolGroup00/LogVol00; if it
doesn, you'll need to edit those too.

Yes, I would think so.
