Good luck John, I hope the book helps, I'm sure it will.
Here's my method to share, that I recently switched to and the prime reason I have not 3-putted in my last 5 rounds.
I think of my tempo as an archer - one who takes dead aim at the target, pulls the bow back slowly and lets go, meaning letting go of the entire ordeal of putting - you're job is done, just let go.
After choosing my line, intermediate target (which is what determines my speed) - I get over the ball. My playing partners have told me before that I take along time over the ball - saying it's a bad thing, that I'll get the yips - but I don't. What I'm doing the entire time over the ball is actually imagining how I'm going to putt this ball. I visualize my arms and club going back and then watching it go down and hitting the ball. I putt my best when I visualize the ball rolling from point A to point B (B being the hole). Point A however is not my putterhead connecting with the ball, its my intermediate target. This promotes me keeping my head down and still throughout the putt, so that when I do lift my head to see the ball moving - it's already at, or near my intermediate target.
Then I always, always, visualize the ball going into the hole - no matter what. After 'seeing' it drop - I just do exactly what I visualized and let go.
Man, this weather needs to get better soon - I miss the course so much...ah, my girlfriend says I'm going through withdrawl.
