A presupposition is something you suppose to be the case before you even start something. Therefore the first act of anything cannot by definition be a presupposition to the action of the play.
If you are asking whether or how the action in the first act is necessary for the understanding of the rest of the play, this is, I am afraid to tell you, the case in any well-written play. The first act of every play introduces the main characters and lays out what their problems are, which are worked out in the succeeding acts and a final conclusion reached at the end. As Aristotle said, "Every play must have a beginning, a middle, and an end." He was a master of the obvious, Aristotle was.
Hamlet
Only to Yoric, Horatio and Old Hamlet; The rest of the cast gets a lot of flack from Hamlet.[and heccuba~]
At the very beginning of the play Hamlet (the prince of Denmark) is informed by his father's ghost that Hamlet's uncle and step-father (Claudius and current king of Denmark) murdered him (the old king) and married his (Hamlet's) mother, a combination of crimes that he (Hamlet) is horrified to realize. The rest of the play is concerned with Hamlet determining how best to achieve his revenge. He first seeks to confirm Claudius' guilt, after all ghosts aren't considered reliable sources. Having done this via a play-within-a-play-sort-of-trap Hamlet thought to kill Claudius while he was confessing at the altar but at the last moment decided that this was too good of a death for such crimes and thought up a protracted pretense of madness that tore the family apart and left a few innocent people dead. During this time Claudius gets his act together and think up a clever way to do-away-with Hamlet. It gets real complicated at the end and everybody ends up dead.
Hamlet is the Prince of Denmark (that's a country in Northern Europe, between Germany and Sweden), because his father, also called Hamlet, was the king. However, when Hamlet was away at University in Wittemberg, his father died, and before he got back, his uncle Claudius had proclaimed himself king and had married Hamlet's mother Gertrude. Hamlet gets back to find that the country is preparing for war, and some of his buddies have seen a ghost looking like his father stalking the battlements of the castle. For the rest of the story, watch the play.

Hamlet
The only characters in the play Hamlet who are related to Hamlet are the ghost of his father King Hamlet, his mother Gertrude and his uncle Claudius. None of the rest are related to him.
In the exposition of Act 1 Scene 5 in Hamlet, two characters speak: the ghost of King Hamlet and Prince Hamlet. The ghost reveals the circumstances of his death to Hamlet, setting the tone for the rest of the play.

"The rest is silent" were the last words of Hamlet.

Hamlet's final words.
Hamlet is the Prince of Denmark (that's a country in Northern Europe, between Germany and Sweden), because his father, also called Hamlet, was the king. However, when Hamlet was away at University in Wittemberg, his father died, and before he got back, his uncle Claudius had proclaimed himself king and had married Hamlet's mother Gertrude.

It is called "The Murder of Gonzago" or "The Mousetrap" and depicts the murder of a king, whose widow then marries the murderer. Sound familiar?
This line is from Hamlet, Act 2, Scene 2. Prince Hamlet has been told by the ghost of his father, King Hamlet, that Prince Hamlet's uncle, King Claudius, murdered his own brother, King Hamlet. Claudius then married the dead King Hamlet's wife and Prince Hamlet's mother, Queen Gertrude. Since Hamlet does not know if the ghost is truly his father and telling the truth, he devises a plan that he believes will prove if what the ghost has said is true. Actors have come to perform at Elsinore Castle for King Claudius and Queen Gertrude. Hamlet asks them to use his altered version of the play, in order to "catch the conscience of the King." The alteration tells the story of a Queen whose husband is murdered by poison. The poisoner then woos the Queen with gifts. Though she rejects him for awhile, in the end she accepts his love. Hamlet plans to watch Claudius' reaction to the altered portion of the play, and discern from that response if Claudius is guilty. His fear of King Claudius' power, and his desire to shame his mother, Queen Gertrude, is the reason for Hamlet's indirect method of accusing the King. If Hamlet's plan doesn't work, he will still be free to pursue other possibilities.
Those are Hamlet's dying words.
