Are you running the HDMI through the walls to the projector? if so, get an in wall cable. Get something HDMI 2.0 compliant is probably a good idea.
The speakers are high sensitivity from what I could find so a receiver alone would be fine to power them.
I'd get a receiver that supports things like CEC so the devices can change the input on the receiver.
A sub is always better. Sound dampening is always a good idea.
