There's a Duke Robillard Book/CD called something like "Groove-O-Rama".
He goes through some older styles of Blues, Jump Blues, Swing and R & B. And there's some nice Voicins and moves to be learned in there.
Shane Theriot also has a good Book/CD on New Orleans style Funk Guitar.
Ha! Well, I got the name wrong. But here is the Duke book:
Haven't really looked at this one, but I like Dave Rubin's stuff I have seen:
As I recall this book, it had quite a few interesting rhythm ideas too:
Of course, some Drumming books might be a good idea as well. Steal some Hi-Hat Patterns, and maybe learn to do Rudiments on the Guitar as well?
