This should be pretty clear once you actually do it. More info below.

No need to measure. Just break off a short piece the width of the bearing
shells. Use one piece for each main.

No. Do just the mains in one step. Do the rods separately. I recommend you do
the rods with the crank OUT of the engine. I know the rod might turn. but
it's a whole lot easier than when the crank is in the engine.

Just compare the width of the squashed plastigage stuck to the crank or
bearing to the widths on the scale. when you get a match, or close, then that is
your clearance. Just do it and it will be clear.

The plastic squashes to make it wider than when you placed it. The squashed
width indicates the clearance.
