We do use the typical complement of in person user testing (headed out to do some today) and obsessing over Google Analytics data. Right now our biggest issue is IE performance, but we also have some other UI elements that confuse people that we are trying to resolve (often think clicking on a product will add it to their favorites list). I'd love to hear more about your navigation issues. If you are so inclined, please email me (rich@stylous.com) some more information about the issues you faced.
