Ok- I think there is a common element to all the plans thus far that is suboptimal, so I'd like to bring it up before plan finalization.
Johann. He should be in the library, not the research branch. It's a waste of his skills.
Point the first: he is the *most* dwarfy wizard besides us here. Putting him in an organization that is wizard (and elf) focused isn't using that. Putting him into building the library, where 90% of the work in the first bits is going to be dwarves with picks is going to smooth things for us a lot.
Point the second- he's not all that good at research. He banged his head against the rattling gun for ages without results, got the we wrong, and he is focused on the aspects of chamon least useful to us with waystones.
So I think we put him in the library. He's got good Diplo- he was the handler for the ducklings until we're had time for them, and he can serve as on-site security against any heavy hitters that randomly show up. And as a disciple of the pick, he's pretty neutral with the book priests.
Plus, offering him implicitly the promotion to head Librarian in the future gives him a clear, prestigious career path. It's a a way of showing him that his loyalty to us is being rewarded.
If we need him for a spell or as a party member, he's easy enough to bring in as a contractor.
As far as the EIC goes, I like Eike, but that can wait a turn without much issue while giving agents stone time to work in before we use them is good.
