getting ready to prep car for paint and bodywork questions

i just got my 340 home, and now plan on doing the body work and prepping for paint.
first question..... how do i get the front and rear windsheild moldings off without bending them up?
how to get the drip rail molding off?

to make a decent driver, should i remove the engine in order to paint in the engine compartment?????????????????

i will be asking a ton more questions as i go. so please bear with me.lol
