Do you remember what the first card you made that got printed was

It was three cards in Alliances: Gustha’s Scepter, Library of Lat-Nam, and Soldier of Fortune. I also named Force of Will. I didn’t like the name it had, knew it was going to be the hot card from the set, and said it needed a better name. The person in charge of the name said, “Come up with a better name and we’ll change it,” so I did.

How does Far Out interact with Library of Lat-Nam and other modal spells where my opponent chooses?

It only impacts modes where you choose.

Does R&D's recent leaning away from effects that cause library shuffling mean I should give up hope in a Soldier of Fortune reprint?

Of possible reprints, Soldier of Fortune is low. Little trivia - Soldier of Fortune (along with Gustha’s Scepter and Library of Lat-nam) is the first design I did to see print.

What was the first set you designed cards for that made it to print? (Or; what is the first card you designed that saw print in a Magic expansion?)

I designed three cards that were printed in Alliances: Gustha’s Scepter, Soldier of Fortune and Library of Lat-Nam.

So there are a number of library cards in Magic (Library of Lat-Nam, Library of Alexandria, etc.), but the only two librarians are an orc and a horror (not exactly who I'd want in charge of a library). What's the deal? As a librarian who plays Magic I'd love for their to be more librarians in future sets!

You’re forgetting Phyrexian Librarian from Unhinged. : )
