LOL girl, I was in your position last year. I never though about going to USNA until my junior year, and completed the whole application process by myself. I literally turned my nomination packets in the day before they were due because I didn't know that we had to turn in separate information haha. But it was definitely a cool learning experience.
Anyway, I joined these forums just in time! You have too. If you have any questions, we are here to help you. They sure as heck helped me! Just make sure you're basic preliminary app is filled out at this point and you're working out a ton, getting good grades, and getting good SAT scores. Next step will be turning in CFA, recommendations, & scores. THEN, start getting nomination packets ready .... you'll be fine :]
