I know this probably isn't what you wanted to hear but there really isn't anything that you can get in the books that you can't find on the internet for free. My modeling has improved drastically mainly because of the things that I learned on forums like this one.
If you really want to get a book I'd suggest that you get books about specific planes that are made for modelers. Those books usually have photos of areas on the planes that are important to modelers.
"Detail & Scale" makes some good books featuring Navy planes. I just used one to help me complete an F/A-18F.
