As others noted best way to learn is to use it. Pick any open source you like, compile and test it, learn it's code, try to fix some bugs or implement features, ask questions from other developers, get feedback on your code. That way you'll learn all caveats of practical C++ development and tools. Additionally while traditional and more detailed books already posted here I'll just add one I personally liked: Discovering Modern C++ by Peter Gottschling. It's had exactly information I would expect be needed for person who already have reasonable experience in programming, but want short introduction into C++. Disclaimer: I'm certainly not someone you can call experienced C++ programmer since I just developing and manage open source project for 3+ years. So take my opinion with a grain of salt.
