Sounds like a good plan for the NF. I honestly wouldn't worry about limiting his time on the breast until you get it pushed out til early morning (i.e. 4-5am). Once it's there for a few days, then start to gradually reduce it or just do wake-to-sleep to see if you can get him past it.
As for capping the naps, I would start by pushing the afternoon one out to 3pm and letting him sleep an hr til 4pm and keep the same BT. After a little while you'll need to cut that one down to 45min and maybe start pushing the morning one out a bit to discourage the EW. 9:30am is pretty early to have a nice big sleep, so he doesn't have much incentive to sleep later, iyswim.
HTH, let me know what you think.
