There’s no universal answer to it, as it all has to do with what habit can you install for yourself that will ensure that you are reminded of the “pending” things to get done “sometime this week/month” One approach would be to put the checklist on your Weekly Review, and when you notice that something needed to be done, clarify the next action, and park that on the appropriate action list, with a due date by it (e.g., confirmation calls and your student’s lesson plan), and perhaps another notation on the calendar for the day it had better be completed by. You could also put it on a “Daily checklist”–either on a Post-it® on your paper calendar you move day to day, or a repeating attached note on a digital calendar entry daily.
It’s tricky, because you will go numb to the trigger if you 1) look at it too regularly and don’t make concrete decisions when you do, or 2) miss looking at it when you should.
Truth is, each of your various activities, because as you say they are so widely different, might need a different kind of triggering mechanism. Some things wouldn’t need a note, because their very presence would be sufficient reminder something needed to be done (e.g., cat litter).
