#8) Medical Tape is best used for taping the mic against the skin. Moleskin Tape is best used to create a thick "sandwich" around the microphone head, and taping it to clothes.
#10) As a general rule, it's good to attach the microphone to the fabric which is creating any rubbing sounds (like a loose outer shirt, for example).
This may not solve the problem, but it's a good first step to troubleshooting.
#11) If it's not possible to attach the microphone to the source of the sound, try taping the source of the sound down (like an unruly zipper).
#12) To hide a transmitter pack from view of the camera, here's two ways to do it:
Clip the pack to the underwear and then tuck the shirt over it (a great solution, actually).
OR, place the transmitter in the subject's pocket and wire the microphone behind the belt, using gaffer / medical tape as needed.
