Awww, he is adorable! Congrats on your new baby. What an exhausting and exciting time for you. Things will get much easier after about a month. For now just hang on to your seat, and join all the other sleep deprived puppy moms out there.
It is normal for him to scream in the kennel. He will get used to it, but in the meantime don't ever let him out if he is screaming. Wait for him to be quiet (even for a few seconds) before letting him out. If he starts crying when you walk towards the kennel to let him out turn around immediately and walk the other way or turn your back. Then walk toward him once he stops crying. If you do this enough he will learn that he only gets out of the kennel if he's quiet. You should also feed him really yummy treats when he is in his crate. Feed him a treat every times you put him in. Sit by his crate when he is quiet and feed him treats through the bars. You can also feed him his meals in the crate. He will learn to love it in no time.
As for crate games, I would throw treats into the crate and let him go get them. Do this several times a day for a few minutes and don't lock him in during this game. You can also throw toys into the crate and let him chase them inside. Eventually he'll begin to see his crate as a fun place to be.
For potty training take him out after playing, eating/drinking, and sleeping. He will need to go frequently. If he has an accident in front of you clap your hands and immediately pick him up and run him to his designated potty area. Bring treats and reward him when he goes outside. If you find an accident just clean it up. He won't remember that he did it.
Most importantly, have fun with your baby. It can be so overwhelming in the early months, but believe it or not, the time will come when you actually miss these days. They grow so fast!
