Run optical cables from your 360 and DirecTV if possible - that will give you the best audio - I recall that receiver not being able to process HDMI audio...
Then connect your HDMI/ component cables to the Samsung, and you're good to go.
Your best bet for optical cables would be from www.monoprice.com - they're dirt cheap and ship really quickly.
