I would recommend (if it hasn't already been done on your car), all prices DIY:
-brake fluid - $25
-tranny fluid - $70
-diff. fluid - $40
-radiator fluid - $40
-spark plug - $35
-cabin air filter - $20
-intake air filter - $15
-fuel filter - $20
I would also take a look at the brake pads and rotors while the car was raised. If the pads are worn close to the point where they will activate the sensor, replace them ($40 per axle). If the rotors have a significant lip along the outer edge (from where the pad could not make contact and ground the inner surface down), consider replacing them ($80 per axle... and for the love of God, use anti-seize compound when putting the new ones on).
While you have most of the shields off under the hood when swapping plugs, I would check out the air intake duct all the way down to the ICV. Feel for holes, tears, worn or melted areas, etc.
You could also do a "Hot Soak" on your engine. Search the forums for this nifty $25 tune-up.
