1. Supplements. I notice that almost without exception they have percentages in the thousands of the daily value of whatever nutrients. Why so much? I don't suppose the body absorbs more than a small fraction of that, right? And if it did, wouldn't it be overwhelmed and intoxicated?

The daily value is just a number that the FDA made up.
There are no studies that really provide you with accurate number that tell you how much of that stuff you need.
Most thinks in nutrition are just guesses. No one has completely figured out how the human body works.

6. Protein: Someone told me recently that protein from something like, say, black beans, can only be absorbed if you eat it with something like whole grain or soy, to make a complete protein. If this is true, why?

Proteins are aminoacids that are arranged in a certain formation.
The human body has to break down the proteins you eat into animoacids to afterwards make his own protein.
Humans mainly use 20 different amino acids to make protein (in some case a additional protein is used).
Black beans alone won't give you enough of all 20 different animo acids to make your proteins. Black beans will use some animo acids more than they are used in humans and some less and maybe even don't use some of the 20 that are used in humans at all.
