I was pretty impressed a couple of years ago when Buzz decked that guy. Here's the situation, as I recall. This conspiracy nut had been writing that Buzz et al. faked the landings - in other words, that Buzz was a liar. Then one day when Buzz was walking along minding his own business, this guy comes up and taunts him with "will you swear on this bible?" Buzz did the honorable thing and decked him.
Even worse, Bart Sibrel (the man whose face intercepted Buzz's fist) lied to Buzz saying he was from some legitimate news agency to set up an interview. Buzz and his daughter went to give an interview and Sibrel ambushed them, jumping out of the bushs, sticking a Bible in Buzz's chest and demanding he swear on it. Buzz tried to just walk away, shielding his daughter from the over 6 foot 200 something pound Sibrel but Bart wouldn't let it go. So Aldrin slugged him. Sibrel staggered back and Buzz escorted his daughter away. The local police department decided not to press charges against Buzz.
The kicker is that just like the sleezeball reporter in Die Hard, Bart's first reaction was to ask if the cameraman "got it." He was obviously just in it as a publicity stunt. Note that Sibrel believes that Aldrin and Armstrong don't give interviews and that this is evidence of a guilty conscience... actually they don't give interviews to conspiracy theorists, and I take it as evidence that they don't like dealing with lunatics.
As Ed mentioned, Bad Astronomy has vast amounts of info on this. There were several threads on the BB over there at the time that have more info that I can currently recall.
As to 1) well, it's damned if you do and damned if you don't. If NASA does nothing they get complaints that they're not answering the questions, if they put a book out on the subject they get complaints that they're making it seem like there's more to the story than there really is. I'm not sure why exactly they pulled funding from the book (was going to be written by Jim Oberg, IIRC), but I think the main reason was that it would be seen as legitimizing the moon hoax people's position (i.e. "See, NASA had to respond to us, we must have a point!")
For #2, no earth or NEO based telescope has the resolution to picture the equipment left on the moon. See Bad Astronomy for the details, but even the Hubble couldn't do it. It's not a case of just nobody bothering or looking but not finding, it's a case of technical infeasibility.
