Not quite sure what you are looking for, but hopefully this helps.

I starred this question because I loved answering it =)

a) It's actually quite common for modern rock and metal to break away from the blues template, so I'll talk more about 70s style stuff. Looking at it from a guitarist's standpoint (which I am), both styles rely heavily on the Minor Pentatonic scale (root, minor 3rd, 4th, 5th, minor 7th) for solos, fills, and melodies, and use the root, 4th and 5th chords to outline the overall song progression. String bending and vibrato are essential techniques, and perhaps most importantly, both have a very "emotional" style to them.

B) The instrumentation to rock and blues is similar, but blues bands tend to be larger and include things like horn sections and pianos. Rock bands can also include these, but tend to stick more to the tried-and-true formula of guitar, bass, drums, and vocals. The beat in rock also tends to be much more driving than than in blues, played in either swing or straight time as opposed to the swing time used almost exclusively in blues, and with a heavier bassline and drum sound. Blues often relies on space between the instruments whereas rock focuses on "filling the holes." Rock usually uses more distortion and effects on the guitars than blues does, and often uses power chords where the blues would use more complex chord shapes. None of this is set in stone, however, and many bands like Led Zeppelin and The Doors blurred the lines between the two.
