said I didnt need a replacement, it was just brake dust noise. Well, they're clean and still squealing. Now what? Oh yeah, and 3 of my wheels are bent and need to be replaced ASAP. RF is so bad that tire pressure is low and car is pulling to the right. Great...

Re-bed the brakes to get an even tranfer layer on the rotors. Stoptech.com has some good info there on how to do it properly.
If the squealing isn't from an uneven transfer layer, it might be from the brake pads vibrating against the pistons/calipers, causing the rotors to ring. You can try anti-squeal paste/spray on the back of the brake pads. This adhesive helps the pistons stick to the brake pads. If you don't have that, and happen to have high-temp anti-seize paste, you can put a very thin layer of the high-temp anti-seize paste just where the piston meets the back of the brake pad. You need to be careful with this stuff, though, because if you put too much, it can get on to the pad material, which would create slippery brake pads. I don't like the anti-squeal spray because I swap out the brake pads regularly for track days. It makes the pad backing all sticky. So, I go with the high-temp anti-seize paste, which sometimes helps and sometimes doesn't. In my experience, solving squeaky brakes often times involves black magic, unfortunately.
Finally, which pads are you using? Some compounds are more notorious for squealing than others. And if you have a squeaky pad, then there is only so much you can do...
