Paint the mirror covers, remove roof rack (unless you use it), remove side molding (cant tell in the pic if you have or not). Interior/exterior LEDs and HID upgrades are cheap and easy.
Since you have mirror turn signals, you could pick up a set of TXBlazers LED inserts. Much better than a single T10 LED. You could also look into a projector retrofit for the headlights and fog lights.
You could paint your calipers since you have upgraded to SS wheels. Maybe switch over to BrakeMotive rotors when you need new ones.
Have you cut off the resonator? What tail lights do you have, they look aftermarket?
Performance wise I would recommend a PCM tune from PCMofNC.
