How to remove body trim......

[Shotgun28]

I am thinking with my car in the garage just sitting there, I would work on some of the things that were bothering me, including finally painting the trim. Does anyone know if this trim is clue or riveted? And what is the best way to paint the trim, I was thinking a dull black, too glossy would look cheap. Please help.
