Thanks for making this a great thread!
He're some more questions to add in.
One, would any of this change or get easier with a Short-throw shifter kit installed?

And then...

Synchro resistance increases along with that discrepancy, as evidenced by the difference in resistance on a shift at 15 mph compared to a shift at redline.:
Sorry if my math brain isn't making the most of that statement, but by those examples, if I'm shifting from 1>2 what would I want the RPMs to be at if I'm going 15 mph in first gear versus 40 mph? Another way of putting it: would I want lower or higher RPMs for 40 mph than 15 mph?

It's all down to learning the dynamics of any new transmission - part of the fun. It's only crappy when there are other people in the car
So, quick story about that: Once last week, I was first in line at a stop light turning left. The guy behind me had actually been riding my tail pretty closely for the past 20 min. But I had forgotten about him, and on green I attempted a smooth takeoff but instead rolled out like a spaz doing bouncy jolts over and over. The guy behind me came speeding around to the side and glared at me like, "OK I get it, already!" and sped off.
