George,
The chrome trim on the top of the doors is held on by the clips that hold the window felt. They should pry up. Be careful not to scratch door or bend trim! I would work slowly from front to back prying a little at a time with a plastic screwdriver type tool (needs to be stiff).
The side moulding with the rubber insert is screwed in place, just remove the rubber to expose the screws.
The aluminum moulding can be pried off using a thin putty knife slid behind the trim and near the plastic clips (again be careful not to scratch the paint). Just slide behind the trim from the top and pull. If you are painting the car, remove the plastic clips and replace (they are inexpensive). They cannot be pulled out without breaking as they are meant to pop into the hole in the body, but not out.
