Biting is not good and he certainly needs to learn bite inhibition. Check out the sticky on this subject at the top of the training forum.
The rest of it, the zoomies, barking, and growling, sounds like playfulness. Some dogs can be more hyper than others. Daily walks and fetch are a great ways to drain energy. Obedience and trick training are great ways to challenge your pup mentally and encourage him to focus.
My family adopted an adult 85-pound Airedale when I was a teen. I was terrified of large dogs and for the first week that we had Tara, I often had to seek refuge on the kitchen counter because I thought she wanted to eat me. We had a trainer come to the house and explain to me that she was doing a "play bow" and her barking and growling were part of the invitation to me to play. Once I realized what she was trying to communicate to me, we became best friends and had a blast playing in the yard.
