I think you have planned/selected a great group of gear to purchase. I don't know a whole lot about the HTRC charger, but features look great for picking one up for around $62 shipped. I like the power distribution feature as well as the ability to check internal resistance of a pack's cells.
Some of the best places, IMO, that will inform a person to the use of LiPo batteries....
