Do you need OmniFocus to help you through the routine? If not, I would suggest not putting that stuff in OF, as that's just 35 actions per week of extra clutter (I speak from experience here!) If you do want/need it, what you propose should be fine (I do something very similar). If you ever go on vacation, you can use Dan Byler's Defer script to make rescheduling the tasks easier:
