More than likely your problem is with the Shaker 500 stereo. You did state that you pulled radio fuse and it helped. If you search these forums and the web you'll see all kinds of problems. We had 05 GT with Shaker 1000 and we had battery problems to. There is a relay internal in radio that doesn't turn all the way off and allows the amps to stay on and drain the battery. Most people say to turn radio off before turning car off. Others say eject all CD's (not sure why?) then turn off radio, then car.
As far as your battery posts... Go to autoparts store and get small packet of dielectric grease for batteries. After you clean them you can coat both battery and cable terminals. This will help with corrision.
You can check to make sure the alternator is charging by using a multimeter as the car is idling you can check voltage at battery terminals. It should be 13v or higher.
