My serpentine belt shredded itself a few days ago. Since the
supercharger belt has to be removed to work with the serpentine belt,
I replaced it as well.

I took pictures of the process and wrote up a quick guide.

Here's the gallery - http://www.paulstravelpictures.com/GM-Pontiac-Grand-Prix-GTP-Supercharger-Belt-Replacement-Guide

I'll be posting the serpentine belt and idler/tensioner pulley
replacement guides soon.
