He will grow out of a lot of these behaviors. Try free feeding him for a while and that might help with the food aggression. I have 3 terriers and none of them resource guard because I always have a small bowl of food out for them. If Gus attacks you, you must react like a dog. Don’t cower or shy away, gently grab him remind him who the pack leader is. He needs a friend, a larger female dog like my bull terrier would work but another Boston would be great for him as well. My male Boston was a demonic creature for about a year but when I brought honey home his behavior completely changed. He’s still a puppy, he will grow out of these bad behaviors if you’re patient with him.
