While researching solar for my Grandby last winter, I studied LiFePO4 batteries. My conclusion was that the technology was not mature enough for me to tackle.
Best discussions I found on LiFePO4 come from the cruising world.

If you want a very complete discussion on their use for house batteries:
http://www.cruisersforum.com/forums/f14/lifepo4-batteries-discussion-thread-for-those-using-them-as-house-banks-65069.html
Lots of arguing and disagreements that you have to wade through (over 4000 post long), but it and the referenced earlier posts will give a good understanding of the issues.
