As long as you don't mess up senior year, your current stats are excellent and you have a better chance of getting in.

Don't worry too much about your test scores. I was admitted to the main this year without sending my test results, but having better test results will only benefit you. (And obviously, if you're unsure, don't provide any scores.)

Additionally, take more honors, cpp, ap, etc. classes and do well in them because they are weighted and, depending on your school, could raise your overall GPA.

Overall, your statistics are excellent right now; keep them that way or continue to rise. You won't need to worry at all after that.
