It seems Michael Ellis is well liked in these parts. Training positive also seems to get a good review around here. That should get you started.
It is never too early to start training. We got started as soon as we got our pup home. You have likely done some good bonding already with your pups situation. Of course your working on potty training already. I highly suggest crate training.
Find his currency. What is he most excited about? Toy, ball, treats etc. What motivates him right now?
My non-professional advice.
