For the measures that are /C7 C7b9/,

Finger the C7 for 2 countslike this:

3-3-5-3-5-3

with index barred across the third fret and the ring and pinky fingers on the fifth frets--(your middle finger should be hanging in the air)--
Then drop the middle finger down on the A string, 4th fret, like this:

3-4-5-3-5-3--

Play two counts, then lift the middle finger up again--


Was that a fast enough response, Gargoyle?
