The Little MongoDB Book might help. It doesn't answer all your questions but it gave me enough background (albeit MongoDB specific) to learn more. It's also a fairy short read. http://openmymind.net/mongodb.pdf
The Little Redis Book [1] might be better. Redis is easier to pick up and probably more useful as it's more complementary to existing database options.
