Regarding NOMAC tracks - I find myself quite enjoying breaking the album up into "acts" or "parts" by the NOMAC tracks.
It really makes sense and gives the story a much more natural flow (only considering the lengthiness of ACT 1), as well as making the climax-like tracks much more impactful.
Kind of like:
Part 1 - (37:00) tracks 1-10
Part 2 - (25:00) tracks 11 - 17
Part 3 - (16:00) tracks 18-20
Part 4 - (23:00) tracks 21-27
Part 5 - (27:00) tracks 27-34
Might just be because I like to organize things, but it's just a different way to look at the music itself
