There are a bunch of books that will help with all programming: - Code Complete (Steve McConnell) - Pragmatic Programmer - Software Craftsmanship by Robert Martin - Test-driven design by Kent Beck

But the way I have always learned most is working alongside people who were smarter than I am, with more experience, and enough patience to explain stuff that wasn't obvious. If that's not easy in the real world, try contributing to an open source project.
