Can I power the amplifier from a USB port?

Yes. A 5 V USB supply is within the 2.5 V to 5 V range. Never exceed 5.5 V, as this can damage the IC, and use a regulated supply with good filter capacitors.

How should I connect the speakers and audio input?

Connect 4 Ω or 8 Ω speakers to the output terminals and never short the speaker wires, as this can damage the IC. Feed the audio input through shielded cable for the best noise performance.
