Scary looking car you've got there. =) Hehee. As far as the grinding noise, is it only when the brakes are cold? (IE, when they've been sitting around overnight and you go to drive the car?) Mine makes a quiet grinding early on, that seems persistant 'till I brake a few times. It's just the rust and deposits on the brake pads and rotors, if that's the case. If not, I'd say take a peek between your wheels and see if the brake pads are worn down a lot. My car has just under 30k, and I've still got a few thousand more to go on my brakes.
