Is this upstream, kernel.org Linux with Xen support built in? There's not
dom0 support in that yet, I'm afraid. There's work to make a mergeable dom0
patch for upstream but that's still ongoing.

3.2 is newer, more up to date stuff, may introduce some bugs. 3.1 is the
reverse. Since 3.2 is newer, active support for it is likely to be better
for longer.
Once you've decided which stable tree you're going to use (3.1 or 3.2, really)
you will want to get updates for bug fixes. The testing trees let you get
the latest bug fixes and small feature updates - you can get them "as they
come" using hg but they themselves won't have yet been tested! Or you can
just update to well defined and reviewed point releases...
I guess I'd recommend using hg since that's generally the best maintained and
most timely source of the code. Whether you try to grab new patches as they
come or wait until official point releases rather depends on whether there
are any particular patches you need, between point releases.

You need 2.6.18, or a distro kernel that has forward ported Xen dom0 support
to a newer base kernel. Soon you'll be able to use the dom0 pv-ops kernel to
get the latest Linux with Xen dom0 support. I don't think it's quite ready,
even for beta testing, yet but I think it was coming along quickly last time
I heard of it!
