The headset is like a pound or something, people wear much heavier hats. My neck is just as weak as it always was, lol. My nieces have been doing VR since they were 4 and 5. They never had issues. Would just be heavier than a pair of glasses would be.

The monitor is not quite full 4k, but it is more clear than 1440p, so still worth setting to 4k anyway. I mainly just play computer games on it, but you can do anything you want, your computer screen is just a floating window you can put wherever you want.

I do have 2 monitors in VR, only one in real life. I mostly use the second one for like a browser window, if I need resources for a game, or I want to put a streamer or Vtuber on in the background. If you press 'Y' on the controller, the monitors swap places, so I do that rather than looking over at it or positioning them in a way that I can see them both. Rather have the one I'm focused on be a 2000 inch TV at 20 feet away. Big enough that it's still like 80 degrees field of view. Just the right size so I can see it all while holding my head still, don't have to turn my head to see corners.

My real life computer monitor is a TV, it's 4k, but old enough that it only does 60hz. The first virtual screen is a representation of that one, so also stuck at 60hz. But the second virtual screen is 4k 120hz. So for any easier to run games, I play them on that one. Unless my sister wants to watch, she of course can only see the 60hz screen.

Yes you do, unfortunately. After that you don't have to have an internet connection however. Since I am only streaming games from pc this arrangement works for me.
