Once you know how far back and through to swing, the next pitfall is in knowing
what to swing.
Start with your Hands
only. 
Swing continuously...Back and through and back and through and back and through. Keep your Feet Flat and your Head Stationary. The Left Arm should be straight, the Left Wrist Flat and the Right Elbow should bend. Your Body should move only as necessary to accomodate the motion of your swinging Hands.
When you've got this down pat, make the same motion using a dowel. Run the shaft up your the Left Forearm. This will help keep your Left Wrist Flat and your Hands swinging through 'Impact.' Without a Clubhead to flip or a Ball to hit 'at,' your Hands will quickly learn their assignments.
When you can do this, begin making the same motion with a Club (but without a Ball). Grip the Club down a bit, and anchor the shaft against the Left Forearm until you can keep your Left Wrist Flat and steady throughout the Stroke.
When the above steps have been mastered, you have prepared yourself properly for the execution of a Golf Shot.
