First, I wanted to say Welcome to YT!!
I think the above advice is totally right. He's just a chewer (he may grow out of it after teething or he may not). Just get him safe things he can chew and teach him what he can chew and what he can't. He'll catch on pretty quickly.
As for the drinking a lot thing...that's new to me so I don't know. If it is really so much that it concerns you to ask, though...I would strongly suggest speaking to your vet about it. May be some underlying condition making him thirsty all the time or something.
Also, since you've been reading a lot, you know how we gush over new pics of pups..soooo, post 'em if ya got 'em!
