Definitely take your time, go through counseling, make sure it's what you want before you start something like hormones that maybe can't be undone easily. Getting rid of facial hair is a pain in the butt, if you would ever decide to go back : ) And yeah, definitely give the hormones a chance to do their job before doing something like surgery...at east two years (well, for MTF's, idk how quickly T works). But likely, you won't need facial surgery anyway. It seems like a lot of FTM's come out pretty good, as I believe T can change bony structures, unlike estrogen. The fat in my face definitely shifted a little...that change took a bit longer than some of the others (honestly, the first thing I got was a little bit of cellulite : P ). And most definitely, put some hair on that face, and I doubt you'l be misgendered.
Best of luck, it's a long, sometimes frustrating road, but if it turns out to be right for you, it's worth it. If you're feeling happier and more together as a person the more male you present, that could be a good indication. That's certainly how I have felt as I've transitioned.
