I've always done the step and pull, but then I will push the legs back up through the skin and snap off the feet. Not alot of meat on the legs, but if not shot up worth saving. The gizzards, well the yotes get to chew on them. As far as ID goes a few years back they told us to keep one wing, not the head. With the new mixed bag limit, I'm not sure whats reuired to keep now, but I supose if you only had three birds it shouldn't matter.
