I just read the specs on the Sony STR-DH500, it will handle the sound and video from the ps3 no problem. It only decodes DTS and Dolby Digital, no DTS MA or Dolby True HD, but for the price of the receiver you can't expect much more. I don't see a need for optical cables in this setup... I could be mistaken though and if you do need optical calbles they can be inexpensive, along with the HDMI cables if you buy them from a place like monoprice.
