You can skip/rebook Eastside Cafe. I've heard it's pretty forgettalbe. Center Street is fun for the vibes (lots of big band music/Aristocat touches) and the Baymax curry.
Don't waste an eligible attraction pass on Mansion. Its capacity is enormous and can handle even the typical Tokyo crowds. Just hit it in the morning or evening (or use an available free pass on the day). If anything, save that extra eligible pass for Monsters or Pooh a second time, as they tend to sell out first amongst the "free" FastPasses (which I understand is also being wound down - not sure what the end date is).
If Indiana Jones is back open, I'd recommend using your eligible pass there. 20,000 Leagues waits topped out at 50 minutes while we were there, but I suspect the actual wait was closer to 30-35. It was also extremely quiet in the morning and evening, so easy to get on it at other times.
Your DisneySea restaurant choices are perfect. We did the Italian full service (the name escapes me) near the Venetian Gondolas, which was excellent, but I've also heard Sakura is really great. Magellan's was a dream.
