re:front squat grip
some of it is wrist flexibility, you just work on that
some of it is taking a wider grip that you would think (outside your shoulders) and also realizing that for a front squat, you don't have to hold the bar in your hand - you can get away with just a few fingers from each hand on the bar as it rides on your delts.

yes - this makes it challenging to move your grip in order to do the press.

Some people (don't remember if it was covered in this thread) use a grip more like what you would use for the press and squat with it rather than do a true front squat/clean grip on the bar. YMMV.

Other people do a real front squat, stop, move the hands around, do the push press, put the hands back, etc. That is - no attempt to make it smooth or a single movement, but just two distinct movements done back to back - the same way you might do a lunge and then a bicep curl.
