Honestly, I think the best tutorial for programming drums is a couple of your favorite CD's in steady listening rotation. Just pay close attention to the drumming and try to develop a "style" based on what you like to hear. I play drums but they are not my primary instrument. I know what I like to hear on the drums but I can't exactly play up to that caliber. But when programming in DFHS I can be the most bad-ass drummer on Earth. Pretty cool.
On the other hand if you are not familiar with note values and time signatures, you may struggle a bit.
