Getting a tune up tomorrow, what exactly should i check/change. My car is at 88,000 miles and as far as i know has never had a tune up(bought it at 86,000 miles)

 

plugs for sure, i'm not sure if the v6 has wires (v8's have cop's) if it does change those as well. tranny flush, coolant flush, air filter(check it first), pvc valve, change the oil (its always good to do it yourself, then you know the last time it was really done). and you should be good to go.
