Glad it's resolved. I have heard this type of noise from failing compressor clutches, the repair usually being to replace the compressor

Could try Plastidip'ing it a la http://www.fordedgeforum.com/index.php?/topic/11010-plasti-dip-my-grille/

I have used Performance Friction pads on my other cars, and they do work well, albeit dustier and perhaps harder on the rotors.

They list pads for the 2007-2010 Edge:

Part Number Description Position Notes 1258.20 Carbon Metallic Brake Pad Front 1259.20 Carbon Metallic Brake Pad Rear

Carbotech's 1521/Bobcat pads also come recommended by many users in other forums, you can check them out here:
