The English of Shakespeare's day had assimilated the succession laws of male primogeniture to such an extent that the succession of a cousin of a king to the throne when there was a legitimate son around seemed unnatural. The same can be said for two similar plays by Shakespeare, Hamlet and Richard III. In both Hamlet and Macbeth the historical societies that gave rise to the stories did not in fact have the system of primogeniture so in the historical cases the succession of a brother or cousin was not considered unnatural. However, Shakespeare's audience would not have known that.
Lady Macbeth does not convince Macbeth to kill Macduffs family. She convinces him to kill the King at the start of the play, but after that she has no input in the decisions he makes. Macbeth chooses to have Macduffs family killed so that he may seize the Macduff castle for his own. The witches also tell him to 'beware Macduff' when he visits them and so he feels threatened by him. Macbeth doesn't actually personally kill Macduffs family either, he hires the same thugs that he hires to assassinate Banquo and Fleance to murder him.
In Act IV Scene 1 Macbeth, having just heard that Macduff has escaped to England says, "The castle of Macduff I will surprise; seize upon Fife; give to the edge o' the sword his wife, his babes, and all unfortunate souls that trace him in his line." In the next scene we see this happening. Of course Macbeth himself is not there personally; it is his hired murderers who kill everyone in Macduff's family. Fife is the town where Macduff's castle is, since he is Thane of Fife.
Macbeth didn't think Macduff was a threat because the witches said "None of woman born shall harm Macbeth." Macbeth welcomes this good news and, assuming Macduff was born the natural way, Macbeth thinks he has nothing to fear.
The message that the messenger brings to lay Macbeth is that the King (Duncan) is coming tonight and her reaction to this was that she wished that she had more time to plan out what she was going to do. <3 VLA BLOWS "Thou'rt mad to say it: Is not thy master with him? who, were't so, Would have inform'd for preparation." - Lady Macbeth
