I've had several labradors in my time. Super dogs and very easy to train as they want human attention (and food).
Have a look at this http://www.wikihow.com/Clicker-Train-Your-Dog. It's a very useful way to train your dog, reinforcing good behaviours rather than punishing bad ones.
Labrador puppies need things to chew - get him a puppy sized Kong toy and whenever he starts to chew something he shouldn't, give him the Kong. He'll need bigger ones as he grows - all 'retriever type' dogs need things to chew on until their around two and a half years old.
If you allow your dog to dig and chew plants in the garden you'll never have a garden, so until you've got the hang of the clicker training, distract him when he's going to do something you don't want him to. Don't leave him in the garden unsupervised, and enrol yourselves on your local puppy-training course.
Good luck and enjoy him.
