It's a set up alright. Basically if all the parts were going to be in usable shape I would say go for it. However chances are your headliner backing is going to be trash, so as soon as you pull it apart it won't be going back together until you get a new repro fiberglass headliner and have it recovered, when you do that you best make some new sailpanels as well and recover them as well as recover the console itself. It's not something you're going to accomplish in an afternoon. The bonus is you have all the pieces including wiring, light assembly and warning light assembly, it's ugly building an SE from an incomplete box of parts.
If you're okay with driving the car without a headliner for awhile, I would pull the backseat, back door panels, inner drip rail moldings, shoulder harness, sunvisors, inside mirror and front inside windshield molding then the headliner and sailpanels. That will take an hour or two. Then you can assess what you need.
