Lipos and charger for me.

Anything Neu or TP would kick ass, but concider the Elite 35c lipos- very comparable prices:

I dunno on your planned layout, but a pair of 3s lipos might fit better than a single huge 6s, but it does depend on the layout in the end.

As for a charger, something Hyperion flavour fits the bill nicely (built in balancer and easy to use): HYPERION EOS0610I 250W 6S 10A BALANCING CHARGER

Not sure about a power supply, That MRC item Mike sells looks alright for the price, but I'd look around for more ideas- Linc has tons of chargers, he'd be a good guy to ask about it..
