Am I supposed to pre-load the gauge as described in the FSM somehow? Am I actually measuring a 2mm rise in the height of the valve keeper - or a 2mm drop in the height of the valve keeper - as I rotate the engine?

Yep, you've found your problem. The gauge, at rest, won't travel "downward". You must "preload" the gauge by .100" or so and than turn the outside ring of the gauge to reset "zero". Then the pointer will move downward when the valve starts to open.
Don't kill yourself to attempt to set the gauge at exactly .100" or .200" preloaded. The rotating outside ring is designed to reset zero just for this purpose.
