Will the AVR-S770H damage the RC60i?

No. The AVR-S770H is rated for the RC60i's 8 Ω load as it comes.

What impedance setting should I use for the RC60i on the AVR-S770H?

None: the RC60i is 8 Ω, and the AVR-S770H needs no change for it.

Is the AVR-S770H powerful enough for the RC60i?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 16 W per speaker, and the AVR-S770H is rated 75 W per channel. Cinema reference level, 105 dB peaks, takes about 160 W.
