Further means less bright, but OTOH more contrast.
most likely NOT. And TBH, I prefer a MUCH larger screen than 110" from 14'. No question. However, I can see certain people preferring that. I'll note that you get most of the benefit of 1080p with this viewing angle, but definitely not the full potential (need to get closer to around 130" from 14' to do so).
Epsons are quiet for a PJ. Look where the vents are. If they are on the front, and the PJ is in front of you, it will then seem even quieter.
My PJ is louder than an Epson, it's rather low due to setup goals, and the vents are pretty much firing right at my ears, at least if I'm in the back row. Yes, every once in a while do I wish the noise floor was lower, but in any case, I'm not very worried about you.
