Hey Chris,
I think they look pretty good. Most of the un PC'ed area's will be hidden so you wont notice the funky mask job. You might notice the outside of the hub where the sprocket goes, but since the sprocket will be in place it will break up the continuity and take your eye away from it. I wouldn't worry about it.
As for the PC over spray in the threads I would say to run a tap through to clean up the threads, but really who has a tap that big?
Use a pick or a dental scale tool (My hygienist saves all the used ones in her office for me, they work great!) and just do the best you can to clean up the threads. Doesn't look like there's a lot of over spray so it shouldn't be too difficult to do.
