I'll address these points.

1) It's not unusual for a student, particularly a skilled one, to make changes to a technique, to personalize it or otherwise "improve upon" it. This could very well be what Amon does.  Him grasping the back of the neck could be a means of rendering them paralysed so that he could perform the energybending, which would make sense since he has no other way to incapacitate them without using ropes or bindings, which is not always viable.

2) A good point, but you yourself point out that Aang could have tried, but failed, or worse, found that people he taught began to abuse the ability. Aang has had timese where he kept secrets, and he could have kept this one out of shame.  He is still human after all, avatar or not.

3) Same issue with #2. Aang is human, and capable of mistakes or lapses in judgement.  The issue with Yakone could have inspired him to rash action in hopes of dealing with future problems, and only after he had trained some people did he realize that this was not the way to go.  Just because he is the avatar does not make him immune to mistakes.
