What else would be recommended to strengthen my application as I am about to enter my senior year of high school?

You should definitely be taking AP classes your senior year. Colleges want to see rigor of coursework increase, especially by senior year. I suggest you retake the SAT. BU, Santa Clara, Villanova, and UT Austin are reach schools. TAMU would be a target school. Yes, colleges look at more than just GPA and test scores, but in the end those become the most important things for whether or not you make it or break it. Wish you the best!
