Enough testing, time to cut something.  

First I cut out two squares from 3mm Baltic birch, one at 80% power, 150 mm/min and 2 passes, the other at 80% power, 40 mm/min and 1 pass.  The two pass cut was both faster and cleaner with the single pass cut leaving some connected fibers and ultimately breaking when I tried to push the square out.  It seems multiple passes are the way to go for sure, although this will need more real world testing.

My second cut was a small Tintin vector that is roughly 20x60 mm (bout the size of your thumb).  This turned out amazingly!  It is crazy how much detail the laser is able to reproduce on 3mm thick wood.
