Tim,
With regard to cleat position, there is a general standard that the cleat placement should put the ball of your foot(1st metatarsal head) directly over the axle of the pedal. If the cleat it too far forward on the shoe, the ball of your foot will fall behind the axle. This can happen if you are wearing a shoe that is too big. In this position, you will have a tendency to use the great toe flexors to assist with pedaling. Over-use of these muscles will cause a great toe contracture. I know this because it happended to me. All so, you will loose power because your force application will be less stable.
If the cleat is too far back on the shoe, you can loose power because you are not taking advantage of the full length of the lever arm.
Now, to your question of biomechanics and pedaling efficiency. I'm sure we could do a computrainer analysis to evaluate your force production with various cleat positions. I'm will to do that but and it would be a cool study, but anatomy and biomechanics predict the best cleat placement.
With regard to pedaling efficiency, this is an issue of riding skill, not just fitness. Efficiency deals with the ability to produce the greatest amount of work with the least ammout of effort and keeping your power leaks to a minimum. If you want to know your riding efficiency, take a look at my post from 11/05/2005. I described the riding efficiency test. It's a great test.
