Thanks for the advice, Alyssa. I'll come up with a new closing. As for the titles, I've already been obsessively scouring the school's website to find as many mentions of each professor as possible, so I can confirm the proper titles. And I e-mailed the campus LGBT group near the end of last academic year, but never received a reply. I learned from the director of housing, though, that my college has had trans students before. Not sure how many, or how recently, but it seems to bode well for my experience. I think my professors knowing as little as possible about my body is a good thing, and if it comes down to it, the administration seems likely to support me. The housing director even said that if I just want to tell people who ask why I live on a girls' floor, "I may not look like I belong there, but biologically, I do," then that's fine.
