My wife has one leg about 1cm shorter. Three things were adjusted to accommodate this. On the shorter leg a 4mm shim was added, the cleat was moved forward ~ 4mm and the nose of the saddle rotated toward the longer leg by a few degrees.
One book that addresses this is the Complete Medical Guide for Cyclists by Andy Pruitt.
