Nlite is a great tool designed exactly for this. I've used it for several installs, and have created a CD that will install XPSP2 with hotfixes and all my drivers, and none of the extra crap that gets installed by default. It starts up in my LCD's native res, includes all my critical apps (firefox, etc.) right on the CD, and is completely unattended.
