So, I started to button it all back up. 2 things:
1. Why do I have to put the pully back on before torquing down the cover bolts? I did it because it's recommended, but I don't understand the need.
They recommend this sequence so that the seal can center around the harmonic balancer shaft. With the cover bolts loose, there is some float for the seal and cover as you install the harmonic balancer. If you were to tighten up the cover bolts and the seal was just a tad off center - it would result in pre-mature wearing of the seal and a leak.

The tourque spec for these is inch pounds, you can always tighten it up a bit if needed. Using FIPG, you are likely just where you need to be with "snug".

Get it buttoned up, run it and then monitor it closely. All the new parts you put in should be leak free.
