Hi Joe,
As long as you are flexible(ie able to spend long periods hunched over in a cramped space), not a difficult job. Headliner does not need to be removed although the edges might have to come up depending on how the prior install was done. If you are going to the thicker plastic (1/4"), which I'd recommend, you will need to bend/move the retainer tabs that are hidden under the trim rings. If you just remove one of the trim rings it will be obvious what needs to be done.
Good luck, Don
