yeah, that looks like a good set, 30C should be enough, 2S is good to keep it safe, from what i heard those chargers are good. i bought my charger on thier site and its great.
you will have to make new connectors on the batt and possibly the charger (unless you just wanted to swap only the esc connectors) but thats easy.

that is a good site to buy from too, i got my charger in 4days.

that will get you going, just make sure your esc will shut down or alarm once your lipo gets low (must keep above 6V)
