So I went to 2 bookstores today and couldn't find any Ravenor/Eisenhorn books

That's a shame, mate. Ravenor/Eisenhorn (and the sequel, Ravenor vs. Eisenhorn!) are all excellent sci-fi thrillers. It's not exactly high-brow literature but it's relentlessly entertaining and the characters are fantastic. I, too, highly recommend them. It should also give you a great feel of the kind of plots and characters you can use in a setting like this since we'll essentially be playing the typical enemies of an Inquisitor.
