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.
