Congrats, should be a wonderful experience.
I'm hardly the most experienced person here, but I did a trip like that last year. As you probably would figure out, you'll really be fishing mostly for big tuna and wahoo, not really anything else. That should help limit what you need to bring. Your wahoo rod can double for bait making or if you do some yoyo or rockfishing on the way home. Speaking of bait making, we did it almost every night, so bring lots of sabikis and weights (I screwed up on this and didn't bring enough).
If the sharks are bad, you can go through a lot of topshots; I was told 5-10 a day. Luckily, they weren't bad on our trip, but I did lose a couple of fish and some bait making rigs to them--they stole the bait as I was bringing it up and took the bait making rig with it. So either have a bunch of topshots, or bring the components and use the travel time to make some. And if you lose topshots, you'll be losing hooks too, so have plenty of those also.
I might be over-prepared, but I think its also a good idea to bring a big spool of replacement spectra--in case you get spooled, if you can't re-spool your reel its useless.
You'll get more and no doubt better advice from others and by reading past reports, but you'll have a year to get ready
