There is a special tool for undoing the clips that hold the windshield molding on. It slides under the molding and releases the clip from indside the molding. The molding on the quarter panels requires a Phillips head screw driver. The well liner has to be removed and then you need to undo the top where it attaches to the tack strip at the rear. You then need to remove the tack strip. With the tack strip out of the way, from under the top edge you should feel Phillips head screws that hold the molding on.
I am going off my memory of when I did all of this 4 years ago so that will be my disclaimer if my info is faulty.
