Hello oxygen. We've got quite a few past discussions here where we summarized our tips and so forth. Have a look at those and you should be able to learn a lot.
I personally can't recommend any book, I tend to be the adventurous/experimenter type and have learned quite a bit that way. Just to start, three useful principles to remember:
- as the "f' number gets smaller, so does your depth of field
- as the ISO number gets larger, so does the amount of noise (speckles) in your shots.
- as the shutter speed decreases, your pictures will tend to blur more
If you can mentally "juggle" these settings based on the particular situation you are shooting, then you will have the basic knowledge for getting optimum picture quality.
Of course there is the purely artistic aspect that I don't think you CAN get from a book, it's something you develop within yourself.
Following "the book" too closely can hinder your artistic elements because you aren't shooting what you feel, but are trying to copy what you read.
