LiFePO4 charging

Given battery pack of http://www.a123systems.com/products-cells-26650-cylindrical-cell.htm in 3s configuration, can it be charged in CC until 10.8 volts are reached and then topped off in CV mode? Is individual cell monitoring as imprtant with LiFePO4 as it is with "older" Li chemistries?

Any suggestions for IC to manage charging of such battery pack?
Can't really find much information on charging of this type of batteries, so far have only found that it is similar to other Li-something except for lower full charge voltage 3.6 as opposed to typical 4.1-4.2.
