Just do the best you can.
Remember - book them in the order of importance to you!! It may be totally out of day order, but get the ones you want the most first. (Thursday lunch, Monday dinner, Wednesday dinner, Tuesday b'fast, etc.)
Be flexible if you can - you listed 2 MK resort locations - if you can't get 1 for the night you thought, can you flip flop it with the other night you planned on dining at the 2nd location? We have to play around with this all the time. It may not look like your original plan, but at least you will dine where you hoped to.
Also - be flexible with your time - You may have wanted a 2pm lunch, but only 1 or 3 is available. You're reserving these first so you don't have to worry about your FastPass times.
Keep checking back. People's plans change. Something may open - a day, a time, or both. (I plan on taking my 79 year old mother to the California Grill this year. The time we would like to have isn't available. We have an earlier than hoped-for time. It would be nice to dine later in the evening, but, if not, she'll still get to experience it. It'll be ok. We're in WDW!)
As much as I love planning for each trip, this is one part that's as stomach-wrenching as it is exciting. (no pun intended)
