“If my computer puts out 4k video (it does), and I hook it to this TV, can I use the ARC, to then go HDMI to a 5.1 surround? My 5.1 surround can only pass 1920, so I can't go PC --> surround --> TV. (I currently do this, but it limits me to 1920).”

You should be able to go PC to TV via HDMI, then go TV to 5.1 sound system via the E-ARC HDMI port. This should also allow you to operate the Sound system on-off and volume with the Sony remote that came with your TV. Be sure you use HDMI cables that have the bandwidth and conductivity to work with 4K at 120Hz.
