A few setup thoughts that I have for the drive are:

1) play the ball off your left foot/heel
2) tee the ball so that when you address it you can see half of the ball above the top of the driver (use the moulded tees for this, much easier)
3) setup with 60-70% of your weight on your right foot, this should result in your left shoulder being higher than your right.

You want to be hitting the ball on the upswing with your driver, unlike your 3 wood.

btw I use a 9.5 stiff shafted king cobra 440sz
