Are you a lefty or righty?
Also on the hook I'd recommend practicing with your thumb to try to learn how to hook the ball, I learned how to do it from watching the PBA pros and the occasional comment from Randy Pedersen containing information about their releases
For the 6-pin, find a line that you can throw to hit the 6-pin. For me(a righty, I go cross-lane and use my 10-pin target(my 10-pin line goes through both the 6-pin and 10-pin)
