As for bending, lets spell out a c major pentonic
C D E G A we find the 1 2 3 5 and 6
add the blue note to get the blues scale
C D Eb E G A the flatted 3rd or 1 2 b3 3 5 6
Turns out that bends on the 5 into the 6 are very appealing to the ear as well as a bend of the 2 into the 6 with a possible stop on the 5 on the way to the 6.
Take this one step further and insert a #5
C D Eb E G G# A all of a sudden you have instant Led Zepplin riffs. Start on the D and play until the A and bend the A like crazy. This pattern is an excellant one for ripping off a ton of notes in a limited area on the neck. This gives you the ability to shread to some degree, but for the sake of blues leaves a lot of options for filler.
Good Luck!
