It could potentially not be the main belt, it could be the a/c belt, idler, or tensioner. I had squeaking like that and it was the A/C.
Take the drive belt off the serpentine and see if it still squeaks, if it does then you can rule that side out.
If it's the main serpentine there have been threads about how to check pulley alignment with a laser.
Here's a good thread about it: http://www.corvetteforum.com/forums/...right-way.html
