The center of vision establishes the feet position
I will usually focus on my footwork when I first start practicing, because my feet set the foundation for the rest of my body.
The shoulder positions are also very important, and is my focus before my bridge. The feet, hands, shoulders, hips, and head should connect as one unit. The hips should control the head's movement down on the shot, so the rest of the body angles (especially the back) can stay consistent as possible.
The center of vision establishes the feet position, the first thing you want to do is get you vision square to the "line of the shot," so you can see it clearly, and naturally.
I would agree completely CJ. I would simply add that alignment of body (stance, bridge, and head) all have an affect on the above. I know that when I miss it is typically one of the three that you have outlined as to what caused the miss. However, #2 and even #3 can be affected by body alignment. I find that #3 in particular is why I rattle a ball, miss a carom shot, or combination shot. #1 can often result in #3 happening...as can #2. #1 is typically a lack of focus/resolve and confidence.
