You can get 4 new Balo rotors and Mintex pads for about $275.00. Also, do a brake fluid flush. 
I noticed you are in Ohio...here's a check list.
    * Brake Rotors - Front and Rear
    * Brake Pads - Front and Rear
    * Brake Pad Wear Sensors - Front and Rear
    * Brake Pad Retainers - Front and Rear
    * Brake Pad Vibration Dampers
    * Brake Rotor Retaining Screws
    * Ate Super Blue brake fluid (2 liters)
    * Wurth brake cleaner (2 cans)
    * Lubro-Moly anti-seize compound
Porsche dealers only replace the caliper bolts if needed...use some blue locktight and some anti-sieze paste when replacing them.
