As far as putting goes, I think others and me would suggest you read the following link:

It's made a huge difference for me, especially with regard to the problem of pace on the putt. Since I've read it, a few times over now, and thought about it, it just makes a lot of sense. If you've already got the line figured out, and your ball set up for that, then there's really one last remaining thing to do: get your brain to know where the target endpoint is, and have your brain know where the ball is starting from, which is why you focus on the back of the ball. Once you have those two points, the brain can calculate the rest, and it becomes much more like the act of throwing a ball to a target.
When you throw a ball to a target, do you ever have to think like this? Well, I need to take my arm so far back, then I have move my arm this fast. You don't have to do that, consciously, your brain just needs the target and a feel for the distance it needs to the throw the ball. If you start thinking about lots of other stuff, you'll interfere with that unconscious solving of the problem, and things go awry.
The quiet eye routine works to clear the mind of the stuff it doesn't need to make a good putt.
