What kind of flying are you doing where you're expecting to be letting down
w/o power?

I go to idle when I'm abreast of the touchdown point. I finish the
downwind, and fly the base and final legs, without power unless I've
goofed in turning base too late.

And that reminds me: I've often wondered how much difference it makes
if the engine is actually dead and the prop is windmilling, as opposed
to revolving at idle. If I do actually lose engine power, will I sink
more rapidly?

Far less drag on a dead prop than on the windmilling disk, but it
shouldn't matter really. On any unpowered landing you should be making
your altitude and airspeed adjustments in the approach automatically
using the sight picture the configuration of the airplane is giving you
based on the remaining geometry that you're seeing between where you are
in the approach vs where you have to be to make the landing at the spot
chosen.
Much is made of the drag factors between these two scenarios, but as it
relates to the real life situation, it's what you see vs what has to be
done that matters. All you need to be dealing with in a power off
landing is the scenario you've been given.
