Walking them can help keep their energy levels in the house down and keep them occupied. However, proper training is how to avoid the behaviors that you don't want to see in the next puppy.
I am sorry for the loss of your other puppy. I have 3 Yorkies and couldn't imagine my life without them. My 2 puppies (7 months old) shredded a roll of toilet paper today. I laughed and cleaned it up. They are not perfect, but they are so sweet as one is one each side of me with the 3rd one curled up against one of the puppies.
Dogs need proper training and the best thing you can do for a new puppy is give it proper training. I highly recommend a dog training class even if all you can do is a PetSmart class to teach basic manners to your dog. It will go a long way in the future as not only will the dog learn some manners, you will learn how to teach your dog and work with him.
Walking will not make a well behaved dog, just one too tired to really get into much, until they get more energy anyway. Training is the secret to a well behaved dog.
