Tune up needed? How far to go???

sounds like you have just about everything there. at the moment i can't think of anything to add.

btw--last tune up i did, i used bosch plugs

If you're really going to do all that, I would get a PCV valve (cause they're so cheap), use a 180° thermostat, don't forget dialectric grease and anti-seize for your spark plugs (recommend NGK TR-55, Autolite 764, any stock heat range copper plug).

I also would skip on the brake upgrade, get SS lines, change your pads, bleed the system. Install linelock with the money you save from not upgrading brakes.

On brand recommendations, changing tranny fluid is also on my list, but I have Mobil 1 Full Synthetic ATF for it. For brake fluid, any DOT-4 should be fine. For the Fuel filter I used a Fram, but would use whatever was cheapest. Coolant, use the green stuff. With tires, I also wore through my DRs pretty quick and use the normal 555 street tires. I like them a lot and they were only about $105.00 a piece.

Hope that helps.
