An question: I've read that some hams turn the RF gain down to noise level and turn the AF gain (a.k.a the audio volume for non-hams) up in order to reduce the noise (mostly atmospheric, but also QRM) the radio receives. For people who do this, how well does this work?

I've never operated that way in my almost 12 years of being a ham, but I'm willing to try it. Anything that can potentially reduce noise and/or bring up signals is worth trying in my opinion.

@ND3JR I can vouch for this method when operating 40m and below using SSB. It helps with the high levels of noise on those bands and makes weak signals easier to copy.

@ND3JR Try it on your own. It depends on your working-conditions. If you have a very small antenna it doesn't make sense. I like to reduce RF when stand by and for CW.
