Should I create a file on Dom0 and assign it for a DomU for use as swap space or should I just overcommit my system RAM and have Dom0 handle all of the swap?

There is no memory overcommit in Xen.

There is in Linux. And if you don't believe it :) Try to do Bonnie++ in DomU, twice the amount of memory as Dom0, disable Swap on Dom0. And 'host' the filesystem on NFS. Fun for everyone!
