Lori - I'd try to stay close to the park that you're visiting that day when you make your ressies. That will help you get to the park earlier, and will end up minimizing the time you spend in line (they are so much shorter in the AM vs. later in the day). As far as Chef Mickey's vs. Garden Grill, we've done CM twice and GG three times. CM is crazy - loud and busy - and the food is pretty mediocre. There are many characters, but they move fast through the tables. GG is quiet and peaceful, the characters linger a lot longer at your table, and the food IMO is much, much better. If you are choosing between those two, I'd definitely pick GG.
You also might want to rethink the 7am ADR unless you are REALLY early risers. If you are driving, you need to allow about a half hour, but if you are bussing it, you need to allow more like 45 minutes or so. That's an early morning (even for my early risers) at Disney! With the late evening ADRs, keep in mind that you'll probably be seated later than your ressie, then you have to order, wait for food, etc. I'd keep on calling for something earlier that evening (how about Coral Reef?).
