Thank you everyone so far with your comments, they have been very helpful! I understand that you can't just learn stage management, you have to have experiences and learn by trial and error. When I started high school, I knew I wanted to go to college. Most people do not know what they want to major in when they get to college, and in this case I do.
Updates if you are really interested:
School-wise-I think I have figured out the application processes for all the schools, which is good.

I looked at SUNY-Purchase last year, and with out going on a long rant, I had a bad experience when I visited and talked to (I think) the head of the department. Also, I didn't get the whole "Apply as a stage manager, then you have to declare your major again when you are a sophomore (I think)."
Syracuse-I also looked at it last year, I think I might have come into a rehearsal you were working on Daz. I really liked the program there.
In terms of my resume and prompt book, I met with the stage manager of the theater I had an internship at this summer, and she helped me out a lot. My resume is a lot cleaner and clearer now.
Thanks again to everyone who has responded! I love this site, everyone is so awesome!
