Welcome to the club
Make sure if you do the tuneup to get a PCV, NAPA Belden wires, NGK plugs, and a Delco or Denso O2 sensor. The idea is to get a car in tip top running shape before modding. Then your first mod I would suggest is a CAI or FWI. After that I would suggest a Magnaflow high flow cat, and a crossflow muffler of your choice if you want a nice rumble. I have a Flowmaster 80 series on my 93 and I love it. The next step after these mods would be to scan for KR before going further. After you have no KR then its time for the big mods
like cam, rockers, porting and so on. You have found a great place with a ton of info and great people.
