What is the best way to determine the correct crank length for my height and more specifically my leg length?

i believe it also depends on the bike/frame type. For example on fixed-gear bikes used for commuting you would use shorter cranks then on free wheel, to avoid hitting road/curbs etc when taking corners – kristof Sep 3 '10 at 14:28

This is probably going to depend on a bit more than just your height or leg length (though I'm sure a rough idea can be gleaned). Your specific bike (geometry) and riding position will also affect crank length a bit.

Here are a few good links on the subject that go beyond my knowledge on the issue.

Also riding terrain and riding style. Shorter cranks let you pedal over rougher terrain and through tighter corners. – freiheit♦ Sep 3 '10 at 17:53
