cars101.com is a good site to refer to for the maintenance schedule if you haven't already looked at the maintenance booklet that should have been included with the car.
but otherwise, as long as you have done all the major maintenance items, there really isn't much to change. if you don't have all the maintenance records, i'd elect to do a minor service including:
-check for leaks
-oil change (check oil cooler for leaks)
-spark plugs (and check the seals while you're there)
-pcv valve (take it out, check it to see if it rattles, if it does, clean the hose to it, and replace)
-coolant (check the t-stat housing and water pump for leaks)
-transmission fluid drain+refill (cheap insurance)
-differential(s) fluid drain+refill (cheap insurance)
-air filter (check to see if it's blackened)
-in cabin air filter (behind the glove box, might find dead spiders and leaves here)
-tire pressures
-power steering fluid (should be cherry, not brown. you can do a simple refresh by siphoning out from the reservoir, replace with new fluid, turn wheels, repeat a few times until fluid turns cherry and clear)
if you got most of this done already, then i'd say you're good to go.
