Jamie, congrats on the deadlift PR!!
As far as NROL -- I think it depends on how much running you plan to do. If you are going to ramp it up to a lot more than you are used to doing, then you may want to just go on maintenance. If not a major increase in running, then you may be able to move on to Phase 2 with no problem and take advantage of having the next phase follow up on the strength gains you've made.
Is Baby Jruck arriving before you could finish Phase 2?? Because I would definitely plan on going on the "I'm getting no sleep" maintenance routine for awhile!
