If you have a decent sequencer that can handle VST then I seriously recommend EZdrummer from Toontrack. Get a copy on E-Bay for the best price - it's pricey enough but incredible flexible and definitely the best package available (unless you have serious engineering skills and want to go for DFHS). There are loads of expansion packs available too with different sounding kits and libraries of midi files so you can start immediately with no experience programming midi at all. Some day when I'm bored enough at work I will post a review :o
