Removing Cab Trim (and side moldings)

[THE "10" SILVERADO]

Hey,
I was comming up with idea's on how to replace my truck trim or to get rid of it and I came up with that I'm going to keep the cab trim (under back window) and get rid of the side moldings...I'd like to take off the cab trim and polish it up and repaint it but that leads me to the question...how do I get it off without damaging it? is there a like push up and pull back trick or something? and on the side moldings is it the same way? On the side trim I see screws I have to remove but I'm sure there are clips in there somewhere I have to worry about.....

Thanks In Advance
