1. You'll need bluetooth to connect them. But I think you have that covered?
2. The sensor bar does not communicate with anything. It's just IR lights that the wiimote can see! And yes it's called a sensor bar yet it has no sensor, but, that's how it is!
3 and 4. That depends on what you get. There are plenty of battery and USB powered ones available.
As for sensor bars, I'd recommend this one, since it's an officially licensed wii u sensor bar, and has AC and battery power: https://www.amazon.com/Official-Nintendo-Wireless-Sensor-Extended-u/dp/B003SVTEUK/ref=as_sl_pc_ss_mfw?linkCode=wey&tag=dolphin-emu-20&th=1
