For the workouts, is it all supposed to be accomplished all at once in the same setting, or is it okay to break it up?

You can break it up if you need to.  That's not a big deal, just make sure you get it all in. I have many clients who work full time or work 18 hours a day, or 24hr shifts and they break up their workouts too. You have to find a way to make it work with your schedule.
