Jenney, Try " Mequiars Scratch X 2.0" It works pretty well on light scratches. Then try a good wax in that same section. Can't screw it up even after a full bottle of wine. Good Luck ! :)
I would go with Intake, tune & Gears. That alone should make the car feel like you added 100 more HP. See how that feels Then maybe pullies & Throttle body.
