hi and welcome to the club..
well besides the oil change me personally i would start by flushing the radiator and putting new antifreeze, a full tune up, plugs, wires, filters (air & fuel ), maybe even the iac valve as they are baout $9 at autozone, how are the tires.? dryrotted or no.?
i would also run the car and burn off all fuel in the tank as its in park then fill up the tank and add some gas treatment/ fuel injector cleaner to clean the fuel system and that should do it..
if i missed something then im sure alot of other members will chime in and tell you..
hope this helps
