An intelligent dog needs positive reinforcement training, dumb dogs need to be disciplined.
When he gets down from the chair as instructed give him lots of happy praise and a treat. after doing this a few times he'll catch on. as for the chewing he's a puppy and he'll chew so the things you don't want chewed on keep up, when you find him chewing on something you don't want him chewing on tell him NO! and give him something to chew that you approve of.
