I really love Zak George on youtube. He has tons of easy to follow training from pups to older dogs to breaking habits or forming good ones. It is all positive reinforcement based which I love and seems to get fantastic results. I know he has all the basics you are looking for and tons of extra. I will leave a link for the "leash training a puppy" video just to get you there or you could just search Zak George Dog Training Revolution on you tube.
