Need some drills/help

[xTsUnAmI]

I've been playing on and off for 10 years now and have never been more committed than now. I hit some great shots, but I seem to have the same problems creep in. Sometimes my head will move ahead of the ball on my back swing. This is super easy to tell and not my main issue. I'll get to the top and be way to quick and my head will go forward with my hips causing me to come over the top. I need a good drill to keep my head back while I start the down swing with my hips. If I avoid that my shots are great, but my other major mistake is holding onto the angle between my arm and club shaft too much (especially with driver) resulting in my hands being entirely too far ahead of the ball and an open club face hurting my drives the most. I break nearly every tee while hitting driver but my good ones are still about 270 right now (still pretty wet here in Washington). I still get way to many shots that start at my target line but slice way right of that. Not all the time but what can I do to help. Right now it's just slow motion swings in front of a mirror 100+ everyday almost.
