Personally after I buy a used car I do a spark plug change, oil change, ect... And yes, tr55's, can't remember exact gapping off the top of my head. I would steer clear of a programmer. For just bolt ons like you have I'd pull your PCM and sent it to "Frost" who is a member here on tech who does mail order tunes based on your mods. If you are planning to do a cam or something more than just bolt ons soon then find out where you can get a dyno tune in your area.
