two possibilities, depending on how "into" the details of breaking in they are (do the players really want to make a plan out of the raw data or get the data then skip to the exciting part?)
If they aren't into the strategic planning, I would make gather info checks or diplomacy with appropriate role playing (bonuses for a good strategic ideas of who to ask) Then have them make a few knowlege, profession or just int checks as apropriate to the task. Possibly use the alternate complex skill check rules....
If they want to figure out the weak spot themselves, but you are worried about the info dump, I'd write down all the relevant info (and some irrelevant info, of course

) and split it up into several sections with different info going to different players...
Those would be my suggestions at least. The "distributed info dump" method has worked relitively well for me in running one shots...
