Serpentine belt isn't that hard. 91parkave did a great write up on it. Ur first things id recommend as soon as u can is a tranny cooler. And drop the tranny pan and do a filter change and a trans go shift kit to help with the tranny lasting longer. Also an oil catch can is a great idea as these cars like to eat oil. U bought yours with only a couple 1000 more than I did mine. And you can greatly improve your gas mileage and power buy getting a tuner. If u know what ur doing HP tuner is the way to go. If u don't trinity custom tune from Lew.
