The easiest way to achieve #3 is often to match your backswing length and follow-through length. All putts should be the same tempo (60-80 BPM, somewhere in there) but vary in the length of the backstroke and follow-through.
You want to hit up on the ball slightly. This will allow the ball to get out of the small indentation it sits in on the green. Grass isn't a hard surface, so the ball will sit down. In actuality the ball deforms the grass infront of the ball when it rolls, this is what stops the ball, because it causes a torque that is not 90 degrees from the center of mass. To prove this, ever see a ball roll in a bunker, that's basically what happens on the green but to the extent you really can't see the deformation, and the grass rebounds.
For me, i tend to do a slight forward press since my putter has about 3 degrees of loft on the club. Then i put the ball slightly forward in my stance, and just putt like the ball was in the center of my stance. I think a bad tendency is to try to push your hands forward to much to strike the ball, so you negate the AoA.
But definitely want to hit up on the ball
