It's based off of personal preference, but I typically organize mine based on how often I need to visit my papers/what I need to access most easily. I set my schedule first, scene breakdown, conflict calendar, cast list, crew list, cast/crew contact, etc., etc. My script always comes last in my book, and I usually have a pre-show, intermission, and post-show to-do list placed around the script (pre-show in front, intermission between acts, post-show after.) Definitely try out different layouts and see what fits you best.
