We started our first full day last trip with the earliest seating at Crystal Palace for breakfast and it was very good. The restaurant is beautiful, characters fun, and the food is quite tasty. By your countdown it seems you are going in November? I don't know how long the park is open at that time but I don't like to take away touring time when the park first opens because there aren't crowds then, but if you're looking at an uncrowded time, you should be fine. You could try an 8:05 PS on a non-EMH day or a 10am PS on an EMH day (and tour earlier and work up a good appetite).
We end every trip with a dinner at Chef Mickey's. I think it's wonderful and sometimes Donald appears at dinner (not usually bkft). The sundae bar is fantastic!
