Nice writeup, I just finished doing exactly the same thing as you did and I'm satisfied enough with it. That should be enough new coolant in the car now.
The only problem I opened the bleeder screw on the expansion tank twice. It snapped while I was tightening it without any force
Had to run to the dealership, buy a new screw at $8, the somehow got half of the old one out.
P.S. Not related to coolant, but I highly recommend doing the MT fluid. Mine came out looking a little brownish, and with new fluid, shifts smoother.
