The Left wrist moves more vertically then the right, yes...but you will see a little rolling of the right forarm and slight wrist hinge to coinside with the left wrist hinging up/down.

Top of left wrist and left forarm should always stay in line, yes. If they were not, then you are hinging the left wrist horizontally (left/right) i.e. swatting.

V of the right hand pointing over center to left shoulder.
V or the left hand pointing center to right shoulder.
All depending on your desired strength.

So getting the right hand more on top of the club is the desired position. The right now gets to be used like a hammer pushing down on the club...the Up/Dn action. There is no need to have any side-to-side movement, so any grip position "from" the side is a waste of potential wrist snap and action.

The feeling I like to instill at setup is the ability to use your hands to take the club and push it straight down into the ground. Lift straight up, and pop it back down. When your grip feels comfortable and solid there, you are ready to hit the ball.
