Welcome to the club. Besides the normal things like, fuel&air filters, cap, rotor, spark plugs (use A/C Delco's) fluid changes I'd take off the throttlebody and clean top and bottom with a soft toothbrush and throttlebody cleaner(don't use carb cleaner). Take the IAC valve out of the t/body and clean the pintle, they get carboned up with the t/body cleaner also.
