I dont have any good way to translate how a slope on the green feels and looks into an estimate of the break.
Putting is so personal you will likely get a lot of different answers. Most all golfers struggle with it, even the tour pros, and I am not a wonderful putter by any means, but I have been improving slowly. Here are a couple of my thoughts.
A smooth stroke is mighty important and many say you need to be accelerating the club through impact. I'm not sure acceleration is necessary, but I do believe you must not be decelerating at impact.
I think it is critical to consistency that you not manipulate the club face with your hands or wrists during the stroke, but swing from the shoulders with a quiet lower body as you mention. This will generate a curved putter path, though it may feel straight back and through. DO NOT FIXATE ON THE SWING PATH! It will drive you nuts. All that really matters is having the putter face aligned at impact. A lot of people are finding the fat grips help to control this hand manipulation.
I would like to give Aimpoint a try, but a lot of good putters have gotten there by practicing. Learning how much break to account for is similar to learning how hard you need to hit the ball for a given distance. I agree that break is a function of slope and distance, but velocity is also a factor. A putt that is rolling pretty fast won't break as much as when it is slowing to a stop, it is inertia at work. So if you are confident, you can "take some of the break out" by putting the ball a bit harder, but of course there is a risk/reward factor there; miss and you have a longer putt back.
Finally, I struggled a lot with proper alignment until I learned to get my eyes directly over the ball while aligning. I generally settle in for the actual stroke standing straighter with my eyes somewhat back of the ball rather than immatating Michelle Wie. But I was far less consitant with alignment trying to set up without being over the ball.
Hope this helps. I apologize for typos, I'm even worse on an iPad than a real keyboard...
