Well, as you can see, some of the "surprises" we got were wires that had to be dealt with. This included the porch light switch, the hall light switch and the doorbell.
Of course, we had to relocate the light switches that had been on the wall next to the door to the, well, other wall next to the door. And, the lightswitch for the living room that was now enclosed in a closet needed to be next to the new doorway. It took me the better part of the morning to get all the wiring in place and checked out.
Once that was done, we could patch the ceiling and the wall and procede to step two.
