Just to answer your question really quick, Eames' real name and all sorts of other sundry details were covered by Tabi in one of her earlier fics, A Soul Awake: http://sho-no-tabi.livejournal.com/915.html.

I'd recommend that you read all of her stories, if you haven't yet. Every single one is really lovely, and go over in more detail all sorts of events referenced in this story. You might also want to watch one of Joseph-Gordon Levitt's earlier films, Brick.
