Preparing for a Hedge Fund Position

Hey all! This coming fall, I'll be starting at DE Shaw and Co as a Rotational Associate (which basically means that I'll be spending the beginning of my career doing short stints with different discretionary/back office teams at the firm to figure out where I'll be a good fit). I have a somewhat unusual background for the industry-- studied both math and history in undergrad (with a fair amount of training in econ and game theory on the side), then went to do a PhD in history (which I'll finish this summer.)

I think that I've got something like ~3-ish months to go before I'll move to NYC and ~4 before I start work. I would like to get on the ball as quickly as possible once I'm officially onboard, so I've decided to start preparing for the job and life changes as effectively as I can right now. At the moment, I'm working on studying the basics of accounting (so I can read balance sheets competently), getting a better handle on data-friendly programming tools, and tackling some books about finance, investing, etc (The Black Swan, Fooled by Randomness, Against the Gods, etc).

I'd like to ask you guys what else I should be doing to prepare for my new life. What else should I do to be able to hit the ground running at DESCO? How should I be preparing to adapt to finance world's culture (or a somewhat idiosyncratic corner of it)? And what sort of cognitive adjustments will I need to make to live successfully/happily at a very different income level than I'm used to? (After living pretty comfortably on a meager humanities grad school stipend for six years, I almost fell out of my chair when I heard about my starting comp package)
