The basic theory is, from a quick glance, still valid.

That it still mentions LVM1 isn't usefull for you as you'll automatically be 
using LVM2. (yes, new version came out sometimes in 2.6.x :) )

As for more current howtos:

And via a blog posting ( http://www.vm-aware.com/2008/08/how-to-linux-lvm/ ) I 
found 2 more:

Most people use partitions on a physical drive for the physical volumes.
