What factors are the most important in producing optics with better/sharper resolution?  Is it the glass, the coatings, the collimation, the light baffling, all the above?  Which production is the most important in producing binoculars/scopes with the highest overall resolution?

All of the above. A interesting website is www.scannerforum.com . On this website you will see $3,000 to $125,000 Film Scanners scanning Air Force Resolution targets off of ortho film. (1000 to 11,000 Dpi) Many of these scanners have lenses and many of them collimate light into a single beam and break that beam into its Red, Green and Blue Components as small as 3 Microns in width. (1 Micron = 10,000 of a mm) The Scanner not dependent on lenses perform better because:

 

All Lenses have resolution or definiton fall off from center to edge with a sweet spot in the center of lens. All lenses have the ability to refract light away from the lens or through the lens making coatings very important for light transmission. As well as the quality of the lens glass and the attention of its grinding / polishing / whatever to be able to focus that light as clean as possible with little to no light defraction or "noise."
