Now we enter a more typical 12 bar blues format with Dead Thumb bass. The bend on the second string, 8th fret really only needs to be a quarter bend. What's important is to try and give the bend a little vibrato. This may be tough if you don't have much experience with bending. If this is the case, practice that particular bend for a while, or check out Christopher Sung's lesson on Basic Bends.
The lick in measure eight is not too tough, although it sounds great at a fast tempo. You can play it using only your 1 and 2 fingers, but find a fingering that works for you. Try to hold the chord at the end of the lick as the tab indicates, and use your pinky to fret the E and D on the first string. There's the feeling of a major chord, implied from the intro, so we get an E7(#9) kind of thing going with that high G natural. Good and bluesy.
