I've been a very lazy bunny with lvm, so I'd do something like:

partition the disks as you see fit (say one big part on each).

system-config-lvm
    create PVs on both of the disks
    add them to your existing VG

Nice and clear what you're doing using that, and helps stop me being stupid.

run lvresize to increase the size of /dev/mapper/VolGroup00-LogVol00
run ext2online /dev/mapper/VolGroup00-LogVol00 to do an online mounted resize
of your / filesystem.

That should do it shouldn't it?

Obviously backup everything before hand, blah, blah, blah.
