The Continuation of the Basement Stairwell Walls

I've been hammering away (not literally) on the basement stairwell walls. I must have done at least 4 sessions with the spackle at this point. Last night, I sanded them and washed them down for the last time before trim and primer.
Just a tip - don't play carpenter angry. Don't paint angry either. Sometimes it can't be avoided if you want to get the work done though.

Left side - trim and primer. Can hardly tell there used to be a hole around the light switch.

Trim and primer.

I did not put up the trim "the right way" at all. I wound up using long narrow brass screws (that's what I had, brass is generally the devil to work with) because trying to hammer finish nails had the plaster shaking and cracking, and I didn't need more of that.
I've been trying to avoid taking the right rail down, but in order to paint the wall well, I'm going to have to. Because it's screwed in over plaster, I'm going to try to free the rail and leave the supports on the wall (lest removing the supports wakes a sleeping crumbling plaster beast.)
So, a few more steps forward. Tonight, first coat of paint.
