Chris is The Man with this stuff so he'll steer you right :).
I found one of the keys to be spending a lot of time experimenting with scales, licks, and phrasing on my own. You have to really internalize this stuff and have it become second nature.
In the blues course, a lot of emphasis is put on taking a lick and making it your own and exploring all of the different ways it can be played and make it sound different. This is where you can take a single phrase and get all you can from it without sounding repetative. Pretty powerful stuff that can quickly expand your playing.
Have fun!!
