Bought my first GP yesterday

So the Jeep has been killing me at the pump lately so I picked up a daily driver from Craigslist yesterday. I bought a 1993 SE in Teal with the 3.4, an automatic, and a sunroof. It has 174,350 miles on it and seems to be in decent shape. I'll poke around here and do some forum searches before I start asking redundant questions.

My first priorities are:

Put a stereo in
Get sunroof to open
get HUD to work
intake or tuning for better fuel economy
tires (possibly some 17 or 18 inch wheels to replace the 16s if I can find a decent set at a bargain)

Any ideas or thoughts are always welcome. I am new to these cars but not new to forums. I hope this is a good one as they vary from make and model.

welcome! there is lots of info on this site!
