One way of thinking about this is as the T-shaped skillset. You have familiarity and experience with a breadth of tools (in this case I would think web technologies) but go deep in one or two. Sorry, but I can't help you choose which one. On that list of books you mentioned, you might want to skip to The Passionate Programmer. It discusses some of the questions you're raising here. And FYI your English is excellent. No need to feel self conscious about that.
