Hi,
Suggest you also go to hardware mfg web sites to take a look of their
hardware compatibility with XP, and use the chance to download their drivers
for XP.
First, make sure your hardware and device are ready (with drivers, BIOS
updates - if needed).
Second, do the same for, at least, software that you used most often. See
if they have any patches, fixes, and updates tailored to XP.
Finally, make sure to back up important data and files before taking
actions.
It won't hurt you to be prepared
Gook luck and hope this helps.
