Need some quick help!

[UK_fan_05]

Sorry if this has been mentioned before, but I' am a little stressed for time right now and need some quick answers. I was recently given advice to pick up the Onkyo 606 and Polk Audio RM6750. I need to know what I need to get with the order so I don't have to place another order after I get my stuff in and didn't get everything I need or have to run down to Wal-Mart (No BB or CC for hours away lol). I plan on ordering 1 HDMI cable (DVi Gear) to go from the Onkyo to my Toshiba HDtv or does the Onkyo come supplied with one? Phillips spooled speaker wire 16 gauge 100ft is also in my cart.

Now, I have a X-Box 360 Elite and a PS3 that will be connecting to the Onkyo. I know HDMI takes care of audio and video, but, do I need to purchase Fiber Optic cable? Does it make a huge difference? I want the best sound out of my games and Blu-ray movies, so I want to get the cable(s) if it helps or is the HDMI cable enough or am I just misinformed about everything lol. The cable is a Toshlink and it is on Amazon along with everything above that I' am ordering. If I do need it, do I need to purchase 2 of them, 1 for the 360 and 1 for the PS3?

Here is a link to my television stand. http://www.walmart.com/catalog/produ...ct_id=10752180 I currently have the 360 and PS3 side by side on the second glass shelf. The Onkyo will be on the bottom and with my digital cable box, and my center-channel speaker will be on the top shelf. Just thought I would mention that in case coaxial would be better for me to go with if I have to go with them at all.

Also, if I' am missing something that someone doesn't see that I should get, please let me know. I want to place this order A.S.A.P. and I will be on here pretty well all night. Any information would be awsome. Thanks in advance.
