Use Bare Metal Foil for the chrome trim strips. It's dead easy to use and looks fantastic. It's easy to apply to windshield surrounds, windows, door locks ect etc.
For the raised letters, unless they're REALLY big, hand painting with chrome paint would probably be your only option.
I think the Model Car Garage makes photoetched frets of things that might help - I remember seeing frets with things like engine size designations (427/429/351) and other little bits on them. I can't remember their website address - someone else might be able to help there. I've gotten a few things from them - McLaren detail set, some seat belts and stuff - they're pretty good quality. Have a look, maybe they might also have a set of letters that will fot the trunk lid.
