Yes, most if not all of your energy should be headed upwards, not to the side, and not forward (contrary to common thought). Your wrist snap brings the ball down into the court, so the more energy you can transfer upwards towards the ball, the more that is going into your racquethead speed.
In my opinion, yes, the tossing arm and getting a consistent toss location should be first. Others may disagree.
