I want to recommend the utility XPCreate, which allows you to burn an XP install CD with service packs and hotfixes already applied. Since it took two days to apply all the hotfixes to a recently re-installed XP sp2 box, this is really useful.
It also allows you to put textmode RAID drivers on the install CD, as well. I was quite surprised to be reminded that XP will only load third party RAID drivers off a floppy during the textmode phase of setup (required if you want your windows installation on a RAID). I haven’t made this work yet, but I will certainly be investigating it further.
