Do not allow him on your shoulder until you get his biting under control. This may not be as easy as it sounds because it is natural for them to go to your shoulder or head as it is the highest part of you and being higher means safety to a parrot. I would not put him in the cage for this behavior as that will end up causing you to have problems with getting him in the cage in the near future. Put him on top of the cage if you are right there otherwise anyplace that he will be safe is fine and the closer the better as timing is important in correcting the behavior.
This species of Amazon parrot is well known for being one of the least aggressive of the Amazons and it sounds like his diet is very high in protein, which may be a major contributor to his aggression. I would start looking into feeding him fresh fruits and vegetables such as chop or a cooked food such as gloop for breakfast and for all day foraging and feed him his seed ration only in the evenings.
