The extra horsepower from dual core is always a good thing ;-)  Either dual 
core or hyperthreading allows you to run domUs *concurrently* with dom0, 
which can improve uniprocessor IO performance (although if you're not highly 
stressing the system it won't matter so much).

Most hardware will work OK, although as usual it's better to steer clear of 
the well-known manufacturers who play fast and loose with the specs.  In 
general most stuff that works with Linux should work with Xen - even more so 
for Xen 3.0.

'fraid not.
