Patience and time, patience and time. We always think our tricks should work instantly, but it just takes repetition repetition repetition.
With Calypso, I instituted a rule wherein if she kept nipping at my hands/shoes even after I shoved a chew toy in her face, it meant she was too keyed up to play nicely and she needed some time to chill out in her crate. So I would call her over to the crate, have her do a couple of easy cues to win little treats, and then toss a bit of treat into her crate so she would go in. After a little while either she would be asleep (rarely), or we would try again with the playing! Eventually, she came to see her crate as a Magic Pez Dispenser on one hand, and she learned not to bite people's hands or clothing on the other.
As far as stuff lying around the house, the key here really is management. Calypso learned, slowly and laboriously, not to chew on shoes left out, and my furniture has been safe for a few months, but just this afternoon I lost a stack of Post-It Notes to dog teeth because they were A New Thing that fell on the floor. It might be useful to keep Goose on a tether tied to you or your desk if you can't watch him 100% of the time, or you might consider investing in a playpen/exercise pen. The one I got for Calypso was not cheap, but it has been worth fifty times its weight in...I imagine the purchase price of plutonium is higher than that of gold, so we'll go with fifty times its weight in plutonium.
As for the always biting you right now: always approach him with something to chew on in your hand. If he bites at you anyway, crate time, or you just walk away. It will take time, but he will learn that biting=no human.
