Even though he's in the backyard most of the day, is he really getting exercised? Romping around sporatically isn't enough for some dogs. My Border Collie could be in the backyard all day, he would NOT be satisifed at all and he would get spazzy. We have to walk/jog him 2+ miles every day, play fetch with him for an hour straight in the evening, and he gets to play frisbee, practice flyball, and do recall/down-stay training for at least another hour spread out through out the day. How many hours/minutes every day do you dedicate to taking him outside and really exercising him? Try upping that, or playing with him every day when you get home so that he can relax when he's in the house. Don't reward his jumpy behavior, don't even pay attention to him until he's sitting down, then give him a treat or pet him.
Obedience would also be great! Often, a training collar isn't even necessary (or only needs to be used for a few weeks), after you learn from a good trainer how to work with your dog.
