Thats great that you have another dog that is "showing her the ropes", this will help tremendously. Some other suggestions to research for a new puppy are:

Crate training - if not already done this will help tremendously with housetraining and give your pup a place to cool off and have his own space.

Bite inhibition - Some links have already been posted.

Basic obedience - You can start having your puppy learn basic obedience with treats very soon. There is a wealth of information here on how to do it, but you can start by giving him a treat when he sits on his own and mark it by saying "sit" just as his butt hits the ground. You can also have him drag a leash around (supervised!) to get him used to that. There are lots of fun interactive things you can do with young puppies that will help shape their future behavior. Good luck!
