God she's gorgeous 
8 weeks is standard for a puppy to go home, and most reputable breeders follow that pattern. I know a few that hold on until 12 weeks, to allow for more socialisation within the litter, but I'm on the fence as to whether I agree with that tbh. I think with the right puppy classes etc., they won't miss much learning from their litter mates, and you lose 4 weeks of one to one taking the pup out and introducing it to the world. The window for socialisation is so tiny. But that's a different thread.
Maybe I'm just soft as shit, but I've always had little pups on the bed with me. The crying breaks my heart a little 
As they get older (12-14 weeks onwards) I introduce their own bed, which they generally learn to love as I make it available in the day time, so it's 'their space'. Most will be happy after a week or so to sleep in their own bed and have that bed moved wherever you like. Being soft as I am, mine have always had the option to come and go from my bed to theirs, but I've never had a problem removing them from furniture or separating them into their own bed if needed. They're settled with their own space and know that what I say goes by that age I suppose 
I've grown up with dogs on the beds though. When I was little our labrador would go to sleep with me at 10ish, and then be moved onto his bed when my parents went to sleep at around 1am. I had an awful time settling into the rickety old building we lived in at the time, so he was a huge comfort to me, and was the only reason I eventually learnt to go to bed there
My current dog died two weeks ago and I miss his weight on the bed like you wouldn't believe. It was like sleeping with an enormous dire wolf
