Great position to be in with current velo. BUT, because of that velo at your age, your Coaches will be looking to pitch you as much as they can get away with... Get your pitching instructor to help you define appropriate pitch count limits per game per week etc. Get your parents on the same page of those pitching limits so that they can help manage the health of your arm. Then talk about the limits with your club coach in a way that he's a partner in taking care of your arm. (He also wants to make sure you're healthy, but sometimes it's hard for a coach to manage limits when a game or tourney is on the line.)
Get seriously dialed into your arm care program (pregame and post game). As a pitcher your arm is your value, preserve it.
As Ryno mentioned above, get equally focused in the classroom. College coaches like good grades, they can say a lot about a players work ethic. Players with bad grades become roster issues; coaches don't want the headache. Good grades offer athletes more options. (better academic college possibilities, more scholarship dollars etc.,)
Good luck to you.
