Window trim and paint question

My 68 Barracuda is UU1 a very light blue metallic. I'm thinking about changing the color (Q5 Seafoam Turquoise). This is down the road a ways, but when I get ready to have it painted, the more prep work I've done in advance, the less it will cost me. My guess is that to change the color, the trim around the windshield, rear window, as well as other trim will need to come off. Is this tricky? The only reason I ask is my record on removing front and rear window glass ain't so hot. Mr. Murphy of Murphy's Law has had my number for a long time.
