Okay, now we have somewhere to start; in this case, at the "end".
You don't really have "subs"; you have 3-way main speakers, a pair of rears, and a center. Hook them up like this:
The rectangular speaker is the center (should be obvious): hook up accordingly, and place on (or under) your TV. (keep constant polarity for all speakers: receiver red (+) to speaker red (+))
The satellites are the rears: hook them up like any pair of speakers to the rear-speaker terminals on the receiver, and set them to the sides of, and
slightly behind, your seating.
The big boxes are the mains, to the front L & R speaker terminals on the receiver, and flank the TV, each one 1 to 3 feet away from it, but not as far as the room corners.
Now, you have to find a menu in the receiver that is either called 'bass management' or 'speaker setup' where, because your bass-capable speakers are the mains, you want to set the 'sub' output to 'no sub' or 'off'.
This will redirect the DVD player's LFE signal to the mains. Also, set the 'main' speakers to 'large', so the L & R bass will stay there. You should set the 'center' speaker and 'surround' speakers to 'small', so their bass will also be redirected to the mains.
Now, what you will have is all of the 5 channels' lows reproduced by the only speakers that can handle it; the mains with the 15" drivers, and the .1 LFE channel's bass added to the mains, too.
If you ever get a dedicated sub, you would simply reset the 'sub' out to 'on', but with twin 15" speakers, you probably won't need one for a while. Plus, there are advantages to stereo bass, even though the popular beliefsays otherwise.
Next, you said that you already told us where the multi-channel RCA jacks are, so I'll just say that you don't need to hook anything up to them; they're for DVD-A or SACD or some future surround decoding scheme.
To reiterate on the DVD player hookup:
Audio: RCA cable in digital jack to receiver's digital jack. That one cable should carry all audio to the surround decoder, even plain stereo CD.
Video: Since the receiver doesn't handle S-video, best picture says to run S-video from the DVD player to the TV's S-video in, and an RCA cable from the receiver's 'TV' or 'monitor' jack to the other TV input, and use the TV to switch video.
Convenience would say to use the RCA video (yellow) from the DVD player to the receiver, and another from the receiver to the TV for everything, and do all of the video switching in the receiver.
You might want to try it both ways (but not at the same time) and see if the S-video provides a noticeable difference in picture quality; if not drpo the S-video and use only regular video (called 'composite') through the yellow jacks.
The VCR should be no problem to hook up using two sets of red/white/yellow cables; receiver 'rec out' to VCR's 'rec in', and VCR's 'play out' to receiver's 'play in', color for color.
The PS-2 will hook up basically like a VCR that doesn't record, red/white/yellow, and the CD changer will hook up like a cassette deck that doesn't record, red/white. Pretty straightforward.
With the exception of phono inputs (if you have them), all of the other inputs use the same voltage levels, so the source device doesn't have to match the input's name. It's more so it's easy to remember which input selects which device.
As long as you already have set the DVD player's and the receiver's digital options properly, you should be enjoying a new experience in about 15 minutes. You might want to print out these instructions, by the way.
That should be it. I think I covered everything. Please let us know if you have any trouble, and how it sounds if you get it right.
