Okay, so I pulled the rotor of and broke the glazing w/ some 400 sandpaper, roughed up the pads a bit w/ some 80 grit, and applied the brake quiet goo. Just rode it yesterday for the first time. It stopped the squealing... for about 1/2 an hour. Ahhhh! While I had it apart I checked to make sure the rotor was floating and it appeared to be fine.
