You don't say how you are connecting each of the source devices to the 876;use HDMI if you can. It impacts the answer to one of your other questions.
One thing I am confused about is what listening mode to use for each input. I currently have a 6.1 in-wall speaker setup.
It depends upon the program material, your connection type and your preferences. The 876 detects and displays the nature of any digital input, and you have to decide which processing mode/soundfield to apply, and whether to set a default mode or use "last valid".
The speakers came with the house -- so I have no idea what ohms they are. I left the setting at 6 ohms -- hopefully that is correct. I want to upgrade the speakers at some point.
You can get a rough idea of the nominal impedance by using an inexpensive digital multimeter and measuring the DC resistance. Disconnect the speakers from the 876. Set the lowest resistance scale on the meter and measure by touching one of the probes to one wire and the other to the remaining wire (the color of the wires does not matter). 8 Ohm speakers usually have a DC resistance of < 8 Ohms--usually about 6 Ohms. 4 Ohm speakers will have a resistance of <4 Ohms. Unless you have exceptionally long wire runs or are using exceptionally small guage wire you can ignore the added resistance of the wire. If you are concerned about that search on the net for resistance of wire to find a table or calculator. You will have to know the wire guage though.
Should I use passthrough or 1080p for upconversion? My TV supports 1080p.
If your display is a true 1080p panel and the source is BD then use through
. You can still make color and filter adjustments if needed.
If your display is not natively 1080p then some conversion must take place. By using test disks, calibrated eyeballs, or letting users vote, you should try various settings so as to let the source device do it, the Reon do it and the display do it. Hopefully one of them will look better to you.
The same goes for 720p and 480i material.
