I agree with most of what is being said here....most of all I agree that you should not order a kit. Everyone has a reason for where they order bulbs, mine is Pinballlife. Terry has good bulbs at a great price (non-ghosting ) as well. I order a bunch of frosted white for the playfield and backbox. As for the inserts I color matched except I think on the orange inserts I ordered yellow. I think the best place to start is the inserts, it gives you the most WOW factor. You will see instant results. Although it does take a bit of getting used to, when the side targets flicker now they really flicker. I put red and blue lights at the slingshots near the flippers, when you run the red light and multiball starts and the playfield goes dark they flash red and blue with the topper light spinning (it's very cool).
PM if you like and I can send pictures.
