Right. I've never met a "nasty" Lab, though I have met some who could have used some manners.

As with any dog, it's all about one thing: Training, training, training! A good basic "puppy kinderagrten" class would be the place to start, especially if they've never raised a pup "from scratch" before. There's nothing particularly different about raising a lab than any other dog, besides their propensity to want to retrieve anything all the time. But they get big quickly, so the more training done now, while you have a size and strength advantage, the better!

I bet he's adorable. Good luck!
