Your brake noise problems are probably related to your uneven wear problems that you initially noted. The uneven wear is likely caused by a slightly binding caliper guide pins. When you replaced the pads the did you completely clean up the caliper, including cleaning up and re-lubing the guide pins and moving/mating surfaces? If you haven't, I would start here. As for re-mating the surface, a couple of passes with a flat file across the pads should do the job.
