Annoying Noises

[bstep]

Got a couple of annoying noises going on in the 02 Tahoe with factory sunroof I just bought. Any experience with same, especially elimination, would be great. 1) Air leak noise when it reaches about 60 mph+. Doesn't seem to be sunroof related. Hard to pinpoint source. 2) Front dome light rattle noise. Since there is dead space above the headliner there, which allows room for the inside sunroof cover to retratct, the headliner and dome light "float" so to speak; no direct roof attachment. So, at certain ride/speed conditions that shake headliner a certain way, I get the rattle. Applying upward pressure with my hand stops it. 3) A/C - heater fan rattle noise: Varies with fan speed. Stops when I apply break.
