Great that he loves the crate! When he's in the house and you aren't home, just leave him safe in the crate so nothing gets destroyed. If you are home, close doors and use baby gates to keep him in the room so you can make sure he's only chewing the good toys (kong? Purple squirrel dude?) and not your valuables.
And if he's out in the yard then YOU need to be in the yard too! Only can train if you have good timing and are there to do the training. So if he barks, in he comes until he learns the 'quiet' command
Have you been able to sign up for any dog classes yet? Another great way to get training in and have it be easy and fun.
