I'm on my 3rd Lab (see my pics in the other thread). Almost all the info in this thread is GOLDEN. Our Labs are well trained and with each one we've used different methods of training, so there is proof that there are many different ways to go about teaching your pup. A couple things will remain constant with Labs (specifically Retrievers).
First, they instinctively chew and eat everything in sight. You can do your best with sprays and potions, yelling and/or scolding - fact is, only time and patience will see your dog cease its destructive ways. As others have said, keep him happy with LOTS of toys. You'll soon realize Labs can digest every thing known to man.
Second, Labs are crazy sensitive about food. They are amongst the easiest and best dogs in the world to train (duh, only a few dogs are trusted enough to lead the blind!). Food is their big motivator. But food is also their biggest enemy. I can't count how many times I've seen FAT Labs. Use food as a motivator to teach and you will be rewarded, but be disciplined with it.
With respect to crate training, I agree 100% with the others. It will pay back in spades if you put up with the relentless crying. The whining every night won't last long. Stick with it!!! I promise it will pay off and you'll be so happy pup is comfortable in there.
You've got a gorgeous pup there. He will soon be your best smoking buddy.
