I would probably call at 90 days and book CRT, LeCellier and Chef Mickeys. Then book the rest once park hours are out. You're still close to 90 days, and most of these (that I know of) don't fill up the first day. Or you can book the rest based on your best guess, but can probably change them.
Are you sure you want to do morning EMH? I think I'd make my plan based on the no-emh park. That way, if you add them on, then you can do the am emh and change parks. Also, adding days to your tickets is way less expensive than hoppers, so you can add a day for a little bit, then on your 'rest' day, go to Fantasmic. That way you won't be in the crowded park all day, and you can do DHS another non-fantasmic day.
