Hi Rickory,
a very good read is the Tweakguides guide for Vista and contains a section on this very topic.. You can either download the free copy or buy the 'deluxe version' ( which essentially is the same) get your copy here:
TweakGuides.com - The TweakGuides Tweaking Companion
The guide is very handy for all things vista so hopefully you'll be able to get those burning questions answered. If you still run into problems, please don't hesitate to post back.
Oh, by the way, your going to need something like 'Adobe Reader' to be able to use the guide. Just in case you need to, you download a copy here (again free):
Adobe - Adobe Reader Download - All versions
