NJ,
First of all, congratulations on making honor roll. If your experience will be like my son's and many of his colleagues that I have worked with the first question a college coach will ask you is "how are your grades?" (By the way, the answer to this is not "good" or "okay." The answer is "my GPA is 3.5 (or whatever it is) in the most rigorous courses in my school.") Let the coach determine how good your grades are as they relate to the admission criteria of his school. Just give him the objective facts--GPA and the academic curriculum you are undertaking.
Class of 2015 makes you a rising sophomore. I would wait until at least a year before you contact a coach. Let your sophomore year play out. If you have a killer year on varsity then you will have something to share with him. Fill out the online questionaire at the colleges you are interested in, then follow up with an introductory e-mail or phone call.
If you played JV your sophomore year then I would wait until your junior year before you contact a college coach. You should also prepare a video near the end of your junior year that you can send to coaches.
It's tempting to want to start contacting coaches very early, but really only the blue chip recruits are having meaningful dialogue with coaches before the summer preceding the senior year. Most players start the significant interactions in the fall of the senior year, some even after that.
In the meantime, keep your grades up, keep working on your game and your conditioning, and start visiting college websites--both on the academic side and the baseball side. Good luck!
