I couldn't find a means to change or set the recruits name, so what I did was make the 4 skills I wanted mandatory and set the wilderness spawn rate so high that the areas were just wall to wall recruits. Then I wandered through till I found one with a name I liked then restarted normally. "Hasta" was the winner.
As for the second post, I tried using rage in the name and it worked as far as it took 100% of my priests faith, but it did not apply any extra damage as a result. I tried it with a melee skill and it applied the damage so I'm continuing to experiment.
