It sounds to me like you are not getting any respect(as Aretha Franklin once said) from Bert. Putting him in his crate-may get him off you, but is not really teaching him what to do and what NOT to do. You must push him down, when he jumps on you, tell him "down", and teach him it is not right to do, and also teach him not to bite people. It all has to be done over and over (seems like forever) until they "get it!". If you do not teach him now-you will have a big, heavy, unruly bulldog, who does it to you. He has got to learn that HE is not the boss. He can only learn that by YOU ALL teaching him-just like you would teach a child. Bullies are more mouthy than most(not all) pups-and it takes time for them to get it! NOW is the time to train him......YOu can do it-just have to do it over and over and over-----until it works! He also needs exercise to get some of that excess energy re-directed-but don't get him wound up-get several balls if you must, and keep throwing, or throw other toys for him to chase. Tug of war -he may like-but it is too "agressive" a game for a boy that gets "wound up!"
