3D TV advice

Hey all....am really keen on buying this tv. My amp is the Onkyo TX-NR609, my blu-ray (which I know badly needs replacing) is the Sony BDP-S360. My amp controls everything sound-wise, we never listen to sound through the television. What hdmi cables do I need, and how many? Am guessing one from the amp to the new tv? I will use my PS3 in the interim for £D playback, so will I need an HDMI 1.4 there as well? would appreciate some help & advice.
