Not to be negative or anything, but if you're "not very familiar with 
debian" - you're just asking for a world of hurt in trying to get Xen 
working.
I've found Xen to be fairly touchy to get up and running, and there are 
quite a few subtle interactions with the host operating system (e.g., 
getting grub startup configurations and kernel variables set up right).
With that said:

- for Xen on Debian, be sure to look at http://wiki.debian.org/Xen

- you might consider installing XCP (the bare metal hypervisor version 
of Xen) - not sure if it would run on your hardware or not (note: 
haven't tried it myself)
- if you're more familiar with another Linux distribution, you might 
want to go with its Xen package (OpenSuse, in particular comes with Xen 
pre-configured)
- depending on what you're actually trying to accomplish, you might 
consider another virtualization environment (e.g., KVM under CentOS, 
VirtualBox, VMware, Parallels)
For a production server environment, Xen is the best of the bunch 
(IMHO), but if you're just trying to maintain a few separate images on a 
desktop system, it might be more trouble than it's worth.
FYI: For ANY virtualization, make sure you have a fast CPU (multiple 
cores are even better), lots of memory, and lots of extra disk space.  
And make an informed choice between hardware-assist vs. paravirtualization.
