I track a player, not the ball. You can see when the player is about to hit the ball and you shoot. You will get a lot of misses because the players will anticipate and then the ball doesn't come to them, for example, but you will get good shots this way. I also shoot single shot, not motor. But at am shooting for display and not press, so my expectations are a little different. I don't have to capture the winning point, I'm just looking for a great shot. If I were shooting for the press, I would probably shoot a little different.
I also shoot though the net a fair bit, using my back button as a stop focus. I pre focus before the play since I know the blockers will be within inches of the same place, then use my back button to hold that focus and get some great blocking shots with cool facial expressions. I also usually shoot vertical, and shoot some full body and some waist up.
I like to get low, I think it is a great perspective, and makes the players look larger than life. I mean really low, like even laying down! Shots from the stands, to me, are boring. If I can get a great shot from up there, cool, but I don't spend much time up there.
I push ISO as high as I need to stop action. The noise doesn't really show in prints which is how my shots are normally used. NOTE: I don't do any post, the lab people do all that, so I don't know if they do any noise reduction after the fact, but I don't think they do. I just shoot and hand over the images.
Yours look pretty good for starting out, I think tighter would be better.
