The main thing, though, is that I got that obnoxious drive-side bearing cup off at last! Took it back to the Walk N Roll shop and borrowed the correct type of wrench, the tool that screws onto the axle to hold the wrench in place (I should know the correct name, but my brain insists on calling it a "little tin can tool" and nothing else will stick), a normal axle since a cottered one won't work, a hammer, and the vise again. Then it was merely a matter of beating on it until it surrendered and came apart. I'd already given it a good soaking in WD-40 and then oil, but it was pretty corroded into place.
Once again, I was glad I stuck it out and got it apart so I could get in there properly with both a wire brush and steel wool for a thorough cleaning. Plus there's some hope it'll be easier to remove the next time I want to get into the bottom bracket to clean and regrease it.
Current leading notion for paint colors: dark grey with lighter blue-grey lugs and just possibly glow-in-the-dark paint for the edges of the lugs and my little moon-and-paw-print logo, depending on price; with that reflective clear-coat I've already decided to finish off with to follow. But black-and-silver is still in the running....
