Thought I could maybe help somebody not damage their trim pieces. Mine (22 y.o.) shattered into smithereens on the lightest pull. They are held by tabs but those are not obvious. They are all "vertical". Meaning to remove the trim pieces you need to lower them, not pull them towards the center of the moonroof, as one might expect. Since I don't recall that the locations of the tabs are shown in the FSM and that given the age of the plastic you likely want to be very careful if you would like to keep yours intact, I am enclosing some pics showing the position of all the tabs so you know what to expect and where to pry. Here goes, it's starting from the DS front corner moving towards the PS. I'm pointing at the remnants of the tabs (note that all the tabs are oriented parallel to the main direction of the trim piece - side to side for the front and rear pieces and front to rear for the side ones):
