I'd highly recommend reading The Manager's Path by Camille Fournier. (http://amzn.com/1491973897 http://amzn.com/1491973897) It covers the entire career path for a developer from developer to lead to manager to CTO. I found it incredibly insightful as a roadmap for what skills I'd need and challenges I'd face while laddering up. I also found it useful in understanding the challenges that my current manager is facing and how I could help learn to "manage up".
