Use IPTables in a domU if you want it to do its own firewalling.  Use iptables 
in dom0 if you want to enforce firewalling and routing rules for the other 
domains.  You can even use both ;-)

Think of the domains as separate machines, all connected to the dom0 "machine" 
using crossover cables (on dedicated interfaces).  You can do with Xen 
whatever you could do with that setup.
