bad manners

Hi, I have a 13 month old neutured male jr and just recently moved. I took him to the beach and it turned out to be horrible. Every person or dog that walked by he would growl and bark at. He does this when he's on a walk but not as bad. My question is I don't know what to do. I have tried things the books say to do, and nothing seems to work. He does not get along with other male dogs, but loves people. The only problem is he gets very excited and jumps up on them when were out in public. At the house he sits as soon as you walk in because that is when he will get pet. I have bought a pinch collar, a choke collar, a harness, and just a regular collar and nothing seems to work. Once he goes up to the person he's fine and acts like there not even there, but if I hold him back he goes crazy. We go on a 6.5 mile walk a day and he plays outside for hours so I know he is getting enough exercise. Another isssue we are dealing with is he sometimes acts like we beat him. He gets down and growls and pees. He has never ever been hit so I don't know why this is happening. Please if there's anything you can do to help I would be greatful.
