Setting up multiple drives. LVM vs Directory? Advice needed!

I have a PowerEdge 1950 that I'm going to use as a PVE host.
I have 2 300GB 15k SAS drives in RAID 1 off the PERC 5/i.
My first attempt to install PVE I noticed that the installer partitioned way more storage on the root partition than I really needed (same goes for SWAP). I have this server loaded with 32GB ram. I have two options: use custom boot params to define maxroot, swap, etc. or just setup 2 logical drives through the PERC card.
1st logical drive = 10GB (for PVE install) 2nd logical drive = ~280GB (for local VM storage)
I want to give my VMs as much local storage as possible and I don't really expect me PVE installation to grow much more than 10GB (including swap).
Any recommendations?
I ran the following:
pvcreate /dev/sdb1 vgcreate datastore /dev/sdb1
Then I added the LVM via web interface

I realize that LVM might not be the best solution here as I can only store RAW disk images.
So, should I just reinstall and use the boot params to make install footprint smaller?
Here´s a little tip...

..shrink your var/lib/vz

/etc/init.d/pvedaemon stop
umount /var/lib/vz
fsck -f /dev/pve/data
resize2fs -p /dev/pve/data 48G
lvreduce /dev/pve/data -L 48G
mount -a
/etc/init.d/pvedaemon start

have fun :)
