If this is your first time at the world, I'd skip Planet Hollywood, Nine Dragons, and Liberty Tree Tavern. Probably Wolfgang Puck, too.
What resort are you staying at?
I'd suggest to swap Liberty Tree with a monorail resort meal at Kona Cafe or The Grand Floridian Cafe. I'd sub Nine Dragons with Rose & Crown or Coral Reef. Nine Dragons is the same stuff you'll get at any Chinese-American takeout place - not something I really want to spend time on while I'm at WDW.
Heck, I'd probably swap Le Cellier for Yachtsman because I enjoyed the atmosphere and food so much better there. I haven't eaten at Le Cellier since they changed to signature for dinner, but I definitely wouldn't miss Illuminations for it regardless. Yachstman is just a boat ride away from Epcot and you can be back in time for a GREAT view of the fireworks.
I don't really like Chef Mickey's, tbh. I prefer Crystal Palace or Cape May. The food is subpar and all three times I've eaten at Chef Mickey's the refills have been sparse and slow and I've felt rushed by everyone - including the characters.
I haven't eaten at California Grill, mostly because I've heard its really noisy and the menu isn't really special enough to warrant the price.
If you do a day at DtD, I would put it towards the end of your trip so you have more of a chance to see all the stuff you can buy at the different parks instead of it being your first taste of Disney merchandise.
When I make ADRs for WDW, I really try to think of the my favorite local restaurants and then NOT pick things like them. While it IS Disney, chances are that if you have a really awesome local Italian restaurant, their Italian restaurant won't measure up and so on. It's not something a lot of people think about and its not a tip people really think to share, either. It's just something I learned from experience.
I'd change some of the ADRs to lunch and breakfast, too. WDW is HUGE and you will be doing a lot of walking and the first day you might need the extra fuel from a big breakfast and a break at lunch the next day. Also, the signatures are usually very slow, leisurely service, so you might not want three signatures to take up your time. And definitely build in some leeway with your ADRs, too. They won't come after you if you don't keep them, so throw in some extras knowing you can skip them and its OKAY.
Sorry, I know that's a lot of information to throw at you. =)
