As a former college player I have found that being able to hit your spots consistently with 3 or 4 pitches is key. Forget the fastball, you can hit your corners all you want but great hitters are going to hit the ball where its pitched every pitch needs some movement.
I would tell your daughter to work on a drop ball this is huge. Rises are great but if you miss your spot there is potential for the long ball and it will carry do to the spin on the ball. At least with a drop you will keep the ball on the ground.
As far as college goes, make video and send them out, show the pitches that she has the most control over and keep it simple. Sometimes its not how many pitches you have its how well you throw the ones you have. Play with the batters, get the catcher more involved with the pitches and spots. As a pitcher she should know every batter and where they hit the last at bat, watch their feet, see where they stand in the box, watch their hands and the quickness of the wrists. As a pitcher you have to observe everything, watch them taking soft toss and warming up. Its all mental in the game, he coach can call the pitches but its up to her and the catcher to use that pitch to mess the batter up. Sometimes a coach can't see those things from where they are. Tell her to use her discretion, do not defy the coach but maybe sometimes she will have to take matters into her own hands. She is the stud out there she makes the calls, the game doesn't go if she doesn't throw the ball, this is a great learning experience for her there will be a lot of this in college. I hope that this helps.
