Will the AVR-X1700H damage the R-40SA?

No. The AVR-X1700H is rated for the R-40SA's 8 Ω load as it comes.

What impedance setting should I use for the R-40SA on the AVR-X1700H?

None: the R-40SA is 8 Ω, and the AVR-X1700H needs no change for it.

How many watts does the R-40SA need?

Klipsch doesn't publish the R-40SA's sensitivity or impedance, so we can't work out a wattage for it. Compare the AVR-X1700H's power rating with Klipsch's recommendation.
