I've also tried holding some paper next to the joints when running but can't really see anything. Maybe see if there's some sort of handheld CO detector?
Question 2: I did also find a leak at the v-band joint using the soapy water test, and was wondering what the order of operations is to try to fix that? My understanding is these don't have gaskets?
Question 3: Is it normal for ceramic coated headers to significantly increase the engine bay temperature on the right side?
Question 4: How delicate/sensitive are the o2 sensor wires? I pinched one on my primary o2 sensor when moving it and that might be contributing to my fuel trim problem.

I'm not help on the tune stuff, but let me see if I can help on the rest...
1. Get a smoke stick or incense for when the car is hot and running.
2. V-bands should definitely NOT leak and do not require a gasket. Try loosening both ends, so they can move a little bit, and then tightening the v-band first. If it still leaks after that, it was made wrong.
3. Maybe? More design dependent than anything. Is more of the header tube on the right side?
4. Oddly enough, I've seen where a pinched wire, that look good, caused problems, and another where one had come in contact with a header tube, and still looked good, cause problems.
