"What is a "Death Match" and how do I send a champion to it?"

IIRC it should be fairly obvious when it happens, like a "send champion" button.

"What is up with these proclamations? "Noemon the Centaur Commander shall hereby be known as the prophet of Urbuthre". I don't give a &^$&*^%*!! Or should I??"

You should. In the case of this, it means at that commander to your list of Bad Guys to Kill, since he just got a lot stronger and will now spread your opponents dominion.

"Can you change the names of your commanders? It seems to give default names to everyone and they mean absolutely nothing to me and I keep having to click to see what kind of troop each one is. I remember basically what a Jarl is, but the name given to the specific commander....?"

Unfortunatetly not.

"What is a "Super Combatant"? Is that an "official" designation or something people just call units that are "really powerful"?"

The latter.

"What is a "theme"?"

A set variation you can apply to your nation when creating it, ex Ulm's Iron Faith. Gennerally has interesting effects you can't create otherwise.
