Re focus - close right eye and focus on an object in left eye using centre wheel. Then close left eye and focus same object in right eye using the right eyepiece diopter adjustment. In theory, then both eyes should be in focus and you just have to adjust the centre wheel to focus between close and far away. In practice on cheaper binos with poorer mechanicals, you may find it a bit of an iterative process - when you go back to left eye it is a bit out of focus and you need to go around again tweaking a little. I have a pair of Pentax binos that behave this way (!)
Of course, for the Moon and beyond, focus should be the same - making life much easier, compared to terrestrial viewing - but you may find it drifts somewhat as temperature changes through the evening.
