Personally, I have just the root partition as a normal partition and 
everything else on two lvm groups. I use two groups because I do disk to disk 
backups and I need to ensure that data is on separate physical volumes, but 
apart from that I am always creating, destroying or resizing logical volumes 
as I change my mind about things.

Root is best left  not lvm, because if you have to boot in a rescue disk, its 
easier not having to have to lvm tools around to get at root and correct what 
ever problem there might be.

(and I tend to use reiserfs just because you can resize to a bigger logical 
volume without unmounting the filesystem).
