Which connection choice is best for the best sound? Is the wireless woofer only connected ( to what? )via Bluetooth

The subwoofer is connected by Bluetooth to the sound bar.

I noticed the video should clear dialogue as an option. Is there a mode for dialogue only on the soundbar to isolate voices?

Your best bet is going with the "Voice" setting on the remote, which makes dialogues more audible in shows, movies, and even sports.

What are the individual dimensions of the soundbar and subwoofer separately?

Soundbar is 35.5” long, 2.5” tall, 3.5” deep. Subwoofer is 15” tall, 7.5” wide, 15.5” deep. All measurements are approximate.
