Guys thanks for all your help. It turned out to be the alternator after all. It ended up costing me about $500 to have the dealer replace it. The alternator was $326 and 1.5 hours of labor was about $160.
I looked online after I had gotten it repaired to see what an alternator would cost for that car, since it seemed a bit steep. It was $300 from various online parts stores, so I don't feel bad at all that it cost me $326 from the dealer.
Again thanks for everybody's input. Great site! Keep it up!
