My suggestion is that you find yourself a USBC qualified coach to help you out. This way you know the people have been trained to help people in a situation similar to yours. You can search on the www.bowl.com web site to find a coach.
Kyle, I agree with Coach Frye, you should have some one on the lanes with you to help you make the adjustments. But, there are two main ways to hook the ball.
1st is with a twisting release to impart a lot of spin on the ball. This is NOT recommended for youths due to the strain it puts on the arm and wrist.
2nd is more subtle and easier to control and use very little spin. Your ball should be drilled for your hand, and every hand is different. Once your ball is fit and drilled to match your hand spread and finger size, it will also be drilled so that your fingers leave the ball in the correct order to put a spin on it from the natural swing of your arm. This kind of spin can then be controlled with more or less hook by putting less or more speed on the ball.
So find your coach, get your own ball drilled for you and have fun.
