2c from a recent bride (me!

) and wife of an anti-planner - Don't think of this as THE Disney trip - think of it as a combined Honeymoon and Disney scouting trip. You're there to get the lay of the land, figure out how everything works, and get a taste for it all. Don't worry, you'll be back! Honestly I thought my first trip was the worst (though it was still fantastic) because it was all so strange and new. Now that WDW is "home" the trips are far better. So ditch that "Must Do Everything" monkey that is SO prevelant with first trips.
Now to planning - it looks good to me. Unfortunately Disney, like flying, cannot be done just on a whim. I wouldn't drive up to the airport, say "I want a flight to X" and expect to be on it within the hour. It just doesn't work that way. Same with sit down restraunts at Disney and special shows. Planning is required if those are important. On the other hand it's very easy to overplan, especially if one of you is more a go-with-the-flow type. Fortunately both DH and I are in that second camp so we vacation well together - I make the ressies since I know we need them while he's fairly oblivious to the whole thing. All he knows is that we're eating SOMEWHERE each night. I did a few "would you like to eat at the place with THIS menu or THAT one" and he chose there ... but that's it.
So my guess ... just make the ressies and, if you've got to talk about them at all with DF, treat them as insurance - if you're having a great time at MK and don't want to leave to go to Coral Reef - hey, that's what cell phones and second trips are for. Don't plan each day - if your honeymoon's like mine you'll spend the first two days recovering from the wedding. And we had a low-key one! Just know which days are best for which park (fits on a business card) and go with how you feel that day or whichever bus shows up first. That's how DH and I tend to do it and while we don't do EVERYTHING ... again, what's the fun of going back if there's nothing left to do?
And if you really want the carriage ride and spa time (sounds fantastic to me!) then make them surprises. That's what I'd do since for my DH listening to me debate the merits and get him excited about it only makes him wish he were in another state. However once we're there he's fine and ready for anything. Hopefully your DF is the same!
