Yes peanut butter is ok for dogs, although some do have allergies. I wouldn't give it to him when he does something good though, it should be in a kong or something as it can get stuck on the roof of their mouth if they get too much at once and so on.
I would stick to small treats for treats for comands.
You could try crate training if you can't watch him then he should be in the crate until he is potty trained 100%
How does he tell you he needs to go when he's in the same room as you? you could try a bell on the door and train him to ring the bell to have to go out as well.
