When I got back into racing in 2011 I knew absolutely nothing about LiPo, I had a bit of help from the guys at my local club but mainly I just read this article a few times:
http://www.rchelicopterfun.com/rc-lipo-batteries.html
It's written by a helicopter guy and is quite long but nearly all the info is relevant to cars and it tells you all you need to know about charging, cutoff voltages, storage etc.
Hope this helps
