Set-up Help

[The Morning Star]

So I just moved and figured that I might as well properly set up everything this time, and I need some help...

I have the KEF KHT-3005 speakers, an Onkyo 605, a 60GB PS3, and a LG BD300.
First off, which BD player do I use for this set-up, the PS3 or the LG? Right now, I use my PS3 in the main player and the LG in the bedroom. Any reason to switch?
Any special settings I should use on the receiver?
Speakers: Large or Small?
Sp Type: Normal or Bi-Amp?
Multiplex/Mono: Input (Mux): Main, Sub, or M/S?
Multiplex/Mono: Input (Mono): L + R, L, or R?
PLIIx/Neo: 6: Panorama: Off or On?
PLIIx/Neo: 6: Dimension: -3 - +3?
PLIIx/Neo: 6: Center Width: 0 - 7?
PLIIx/Neo: 6: Center Image: 0 - 5?
T-D: LstnAngl: Wide or Narrow?
Under HDMI settings, do I enable "LipSync"?
Under Analog Multich, what does "SW In Sens" do? Do I set it to 0, 5, 10, or 15?
Also, I set up the speaker distances already and just wanted to make sure that I was supposed to set it based the the center optimal seat?

Thanks for any help.
