Books/links to help manage a development team

My team has recently grown to the point where development process has become as important as development experience and open communication--there's about 7 developers. Though I've managed many technical projects, they've never been a full fledged product, and I haven't been a full-time developer myself since maybe 2002. As such, just about everyone on my team has more experience with formal development methodologies that I do. I believe we do a good job (weekly reviews, good use of SVN+Trac, generally on track with our roadmap, etc), but I'd like to get more up to speed so that I can offer suggestions that are consistent with proven best practices. While I've done well enough picking up things on-the-job, a little push in the right direction would be really helpful. I'm curious if you have any suggestions on books or links that would help me get more current on dev methodologies, given that I'll be leading rather than developing, and that I already have a good understanding of many components of agile, lean, lean startup, and the like...I could just use something more comprehensive and tactical for a project manager/team leader.
