My Mazda 626 recently hit 60,000 miles and I recently had the belts changed because they were starting to show cracks and slipping on occasion, but now that I've had them changed (by a mechanic, not myself) I get the high pitched squeel of them slipping pretty much every time I start it up after its sat for awhile. Any thoughts?
Alternator belt isn't tight enough would be my guess, if your car doesn't have a serpentine belt system. If it does then you either got the wrong belt or you have an engine-driven accessory getting ready to sieze up and wipe out your new belt in short order.
In other words, you should probably get it fixed right away.

Now that I think about it, the last time a mechanic touched one of my cars, he replaced the a/c compressor on my '85 Alliance. He got the a/c work done well, but he screwed up putting the serpentine belt back on; he got it in some sort of alternate configuration where it *almost* fit perfectly, but not well enough that it didn't squeal. That's another possibility.
