Seat height has to be individualized. I like a little flex in my knee even at the farthest part of the stroke. If I drop my heel, my leg is straight, but otherwise there is still a little bend. However others might like it a little different. Regarding knee pain, an old and not completely reliable rule is that pain in the front of the knee = seat too low, pain in the back of the knee = seat too high. However pain in the front of the knee can also be due to "grinding" (high gear, slow pedalling) when you should be "spinning" (low gear, fast pedalling).
I wonder if you time your commutes. You might just be tired all the time because you keep going faster.
EDIT, I see I am repeating part of what RubeRad said.
