Welcome Nate. You've come to the right place.
First of all, I wouldn't remount this plant yet. Not until it totally overgrows the wood it's on. All of my Angraecoides (like Aerangis) are in a humidity controlled wardian case (90-99% humidity) because that is what Angraecoides need. This one (the one you have) comes from Madagascar and the Comoro Islands off Africas east and west coasts (respectively). It tends to grow attached to tree limbs in a moist environment. What this means to you, is if you plan to bring this to flower you will need to keep humidity very high (the bathroom sounds excellent) and you might want to mist the whole plant (leaves and roots and mount) with pure water (not softened or tap water) in addition to the shower steam. The bright window sounds fine. I would also plan on getting some fertilizer and mixing it very weak. Check this site for instructions:

I water all my Angraecoids with water and fertilizer every other day. They are misted with pure RO water every 4 hours for 5 seconds. You might not need that, especially if you take your plant into the shower with you in the morning. Don't forget to place it back in the window, though
