I just started off in a very young startup and we will be a building a team now. So this was my concern too. I started reading Peopleware by Tom DeMarco and Tim Lister, and I'm 1/3rd in it. Highly recommended.
I also found this series of articles about a real person's real experience while trying to improve things in his company to be pretty interesting. http://www.jamesshore.com/Change-Diary/
