I don't really know what to say here. I think the preset names do a pretty good job of explaining what they do. They're supposed to be a jumping off point. Dom's original answer was pretty appropriate, then the question changed.

If you want to learn about the render settings, then you can start with "Help>Render Settings" menu at the top of the render settings window. There's a ton of info on all the different tabs.

Personally, I think the "production" preset is just overkill on the raytrace settings in many cases. And if someone doesn't understand the basics then bringing FG settings into the conversation is only going to muddy up the waters further.
