Also here's a vid series on Groove3 about drum theory. http://www.groove3.com/str/drumming-explained.html You have to pay for it though but there are a couple free sample vids on that list you can check out. I haven't watched the series myself but Eli Krantzberg vids are insanely helpful IMO so it's probably worth paying for a month membership ($15 right now apparently) or buying the download for $25.
Ive watched this, and, having been a drummer for the past 35 years I can highly recommend this. I was sceptical at first but, actually it's a really really good video. Eli explains things in terms of a DAW really well. Worth every penny.
