This picture below was posted by mjw930 and I added some circles to mark the items in questions.
About the items in red circle:
Anybody could direct me how to remove the clips? I didn't see any screw etc and the back of the insulation is glued.
About the items in green circles:
Anybody know what kind of screw/nut noted in the circle? It is a flat screw/nut made of plastic and used to hold down the insulation. I was using an electric screwdriver and accidentally break one of these (flatten the top)
