You seem to have it well covered. Just post back any questions you might have once the gear arrives. The Energies will be a good entry level speaker system for your needs from the sounds of it.

One cable often overlooked is the additional digital optical cable (toslink) sometimes used from HDTV back to AV receiver. It's $5 @ monoprice.com or Amazon, btw. Definitely grab one.
Keep in mind that things like ARC rarely work as advertised.
