Hi onklp
No onklp, their is no other place to tighten the belt up. Their are a few things that can cause play in the serpentine belt:
-Worn Serpentine Belt (replace the the belt with the correct one)
-Worn Belt Tensioner (replace the tensioner)
-Broken Alternator or Power Steering Pump Bracket (Repair the bracket)

The last one (broken bracket) seems to be a common problem with certain years. Have a good look at both Alternator and Power Steering Pump Brackets to make sure they are tight, in place and not cracked or have bolts missing from them. The first 2 are just part replacements. These 3 areas are the root causes for play in the serpentine belt. I hope this helps. Please keep us updated, Thanks.

PS: Just a thought here as well onklp, is to make sure the belt is being installed correctly, If it's not, then it will cause play as well. Here is a link to how the belt should be installed for your year. Their are a few different ways depending on what accessories you have on the vehicle, Figure #16 at the bottom of the page is for your year in the link I have posted here. Just click on the image to enlarge it.

Yes, like matrixx said, double check your routing. Really, there are several different ways of putting the belt around the pulleys and believe it or not, if you were to measure the length of those distances around the pulleys, they are different.
