If there isn't any publically available information, I wouldn't worry about knowing about the firm before sitting down. I would, however, treat it like a job interview. No one in this industry is going to feel like he's getting much out of the time spent answering your questions. He's either considering hiring you or doing a favor to a friend. I'd read up on long / short funds generally - leverage ratios, long / short ratios, maybe know a little bit about prime brokerage and stock loan. If you know which sector (not clear from your post) learn a bit about that - as in recent news, some general background, etc. Something else useful is to talk about a stock you like. That will show (1) initiative, (2) some intrerest in the subject and (3) maybe allow you to answer general valuation questions a little more easily since you will have gone through it on your own.
