Pete, you need to chill, step back and look at your problem. When you hit a good shot, you're normally target oriented, not focused on mechanics. The zen equivalent is the concept is called "no mind" where execution is perfect and you're hardly aware of the act itself.
That said, concentrate on your set up. If you must think of some part of your swing, I'd focus on the transition at the top of the swing, make it syrupy. If you can maintain your spine angle, you should hit a pretty decent shot.
Most importantly, keep it simple. Trying to do too much will aggravate things. Good golfing! :D
