Setup help, please

[zinfella]

I've seen so much info that my little brain is swirling, and I'm still not sure how to setup my setup. So, if I can get all of the needed info in one thread, maybe I'll have enough to do it properly, and TIA to all of the great folks here!

I've got a Panny BD55, still in the box.

I've got a Denon 1404/484 5.1 receiver, that I think I can boost the SW with. Since it doesn't support HDMI, I can use optical, coax, and/or analog. I have plenty of optical cables and an optical switch. I have not set up my 484 properly since I got it years ago because I didn't know any better. Now, this forum has opened my eyes, so I will be setting it up, (I'm also looking, just looking, at this point at a new receiver, maybe a Denon 789 or 889) the way it should be. None of the speaker sizes have been set on my current receiver, and I haven't messed with the SW, so it should be at 0.

So, should I setup the receiver first, or the BD55? How do i setup the audio at the BD55?

Do these settings also work for broadcast TV? Or, must I make audio adjustments when switching from my cable box to the BD55?

I have a 52LG70 LCD TV that has 4 HDMI ports, and I know that when I use the HDMI cable from the BD55 to the TV, I must turn off the audio using this non-HDMI Denon, but I know little else.

I suppose much of this can be simplified if I had a newer receiver that had HDMI support, but, I've already spent for the BD55 and the TV, and my resources have limits. If I can swing a new receiver, I will, meantime, i need to live with what I have, and I need to set it up the right way.

I will keep a sharp eye on this thread so that I don't have to keep coming back here and asking for help to get this going.
