Hi and welcome to YT. Congratulations on your new pup. Most would agree that 8 weeks is a bit young for your pup to come home. I would talk with your breeder about this. If you have not had a puppy prior then I would seriously take a look at keeping him with his mommy for a bit longer. This will give him some more time to learn from his mommy and get a great start on his new life with you and your family.
I would suggest that you give him something of yours so he can get used to your smell prior to him coming home. This will also help in his transition to you. It will also have his mommy's scent on it so it should help ease his anxiety too.
Have you gotten your supplies as far as crate, bed, potty pads, food and water bowls, toys, blankies, clothes-just to keep him warm, etc?
Best of luck to you once he comes home. I like the the Mojo.
Can't wait to pics of him.
