I put another five hours of work in on Sunday.
It turns out there is definitely a correct order to follow when putting on or taking off the plastics. I had the battery in and out of the bike on for separate occasions because I'd missed one of the screws on the fairing (some can only be reached with the headlight off and others will only fit after everything is mostly assembled).
After two busted knuckles, a screwdriver to the palm, running a metal tab through the "webbed" part between my pinky and ring fingers, and a whole hell of a lot of questionable language, I have the front of the bike back on. I've removed the wiring for the rear camera, ammeter, voltmeter, and the HIDs (and relays for them). LED bulbs are now in place for the headlights. I ordered some for the front turn signals, but they're not working. I'll probably swap back to incandescent for those.
Not pictured is a lot of the plastics I cleaned up. I still need to spend some time on the panniers and the big side panels, but just about everything else is looking pretty good.
