I know I need to start from scratch, and I'm anxious for the alignment golf dvds to arrive. In the meantime, I will jump right on the MacDonald Exercises.
Start with the Grip. It will take a few weeks for the correct alignments to become second nature.
As you work toward this end, do your MacDonald Exercises. There you will learn the correct relationships of the Body, Arms and Hands and how they are integrated into a sound Golf Stroke. Study and emulate the Address photos of Larry Nelson . Also, my own Grip and Flying Wedge alignments.
