Firstly, if you only have three speakers, I would avoid using any surround modes that cause the rear icons on the front panel to light up, because that would indicate that information is being extracted and sent to the rear speakers, thereby "lost," which you probalby don't want.

Secondly, the 1050 is fine with 6 or 4 ohm speakers.

Thirdly, a lot of TV shows (especially movies which were originally shown in a theater) are broadcast in Dolby ProLogic surround, which the DPL circuitry in your 1050 can decode into Left, Right, Center, and Surround (monaurial rear) channels.
