How to remove this sun roof and window part
 

I"m sanding down the 84 GSL-SE for painting. My son is helping and a friend will shoot the paint. Can anyone tell me how to remove the exterior door molding along the top of each door where it meets the glass? The inside of the sunroof has a carpet like padded section. It appears attached through some type of plastic pronged affair. Can anyone tell us how to remove that as well? The front bumper is off and when we finish the front clip and doors, on to the rear bumper and glass hatch. We hope to be done by October. Thanks in advance.
