I think you'll get as many opinions as you get answers ! Like so much 
else, there's a large element of personal preference.
Personally, I do all the LVM in Dom0 - so I export several volumes to 
each DomU and use them raw (ie with no partitioning in DomU). It 
makes it a doddle to manage filesystems in Dom0 - though since I got 
into that habit I think it's got easier to loopback mount the volume 
and then access the partitions within it.
As to how to split the system up - it all depends. I have some 
systems with just a single volume. On the other hand, I have other 
systems with multiple volumes so as to split volatile or prone to 
growth (eg mail stores) data from the rest of the system - mainly to 
prevent uncontrolled data growth bringing the whole thing down.
