The main way in which the grievances in the Declaration of Independence were addressed in the Bill Of Rights is that the Bill of Rights explicitly protects individual liberty, and things like freedom of speech, freedom of religion, etc.--al things that the colonists felt had been robbed of them by the British.
They wanted to obtain votes from states that were pro-slavery and by abolishing it they may have ruined the chances of receiving southern states votes for a declaration of independence
Under federalism, It would be both state and federal government that has concurrent powers. These are powers in nations with a federal system of government that are shared by both the federal government and each constituent political unit. Hope this answers the question.
