I thought I'd post again with some finished pics of our new bathroom. We're missing a TP holder as the one I ordered came missing a piece, and we have our new doorknob/back plate to install, but it's essentially done otherwise.
I am happy with the way the room turned out and with the way it fits in with the rest of the house. It looks very similar to our largely untouched upstairs 1920s bathroom (which was originally a dressing room), and the medicine cabinet and sink are virtually identical.
If you want specifics on the things we used, you can find them in my post in the bath forum. Now, on to the laundry room and kitchen! :o)
