Several suggestions come to mind.
First, what is Buster's diet like? In my experience, many nandays become hyper-active when there are too many sunflower seeds in their diet. By contrast, birds who have a diet that is at least half fruits and vegetables tend to be calmer. If Buster is receiving more than about half a dozen sunflower seeds a day, cutting them out could make him calmer in a matter of a couple of weeks.
Second, how regular is Buster's routine? Birds without an established routine tend to be rowdier, especially if their routine means that they don't get enough sleep.
Third, could Buster possibly be a bit spoiled? He sounds like he is used to having his own way. If you don't already, you might try putting him in his cage as soon as he misbehaves. You might also try very lightly tapping his beak and saying, "No!" in a loud voice; parrots understand this treatment because it's close to what they do when someone displeases them.
