If William became king, but died in that role, then the line of succession says that his brother, Prince Harry will become king. Or, if William had children, the eldest male will become king, or if he he had no male children, the eldest female will become queen.
To become the actual monarch of the UK, you have to be born into the royal family - marrying into it can grant you the title of princess, prince or queen consort, but never King, or Queen regnant, such as Elizabeth II.
The same situation happened to the late Queen Mother. As the wife of King George VI, she was known as a Queen, but she was a consort, not a ruler. When he died, the throne therefore passed to his heir, Elizabeth II, the Queen Mother's eldest daughter.
If he dies without children, Kate will be the dowager (whatever her former title was). And then Harry and his line will succeed to the throne. However, if William dies before he marries Kate, then Kate gets no title at all.
Yes, the people will move on .Kate and William are going to remember it forever and so are we, but we will move to something more important then that later.
Once the Queen (Elizabeth II) dies, Prince Charles will become King, after he dies, Prince William will become King, and Kate, as his wife will become the Queen Consort (not the Queen Regent, like Elizabeth is)
Kate Middleton will become a princess when she marries Prince William. If William becomes king, Kate would then become queen. If Queen Elizabeth II abdicates the throne to Prince Harry however, Kate will remain a princess. This would seem unlikely considering William is in line to the throne before Harry.
Unless something happens to William, then yes, they will.

Yes____________I seriously doubt the above, but I am not certain. A 'consort' by definition is the spouse (or partner) of a person, and marriage dissolves at death. So the title 'Consort' would hardly be applicable if King William predeceases her. If she has children at the time of the king's death, she might take the honorific 'Queen Mother', as did the mother of the present Queen, Elizabeth II. If there are no children, there will be a different king and queen, and Kate retaining the position of 'Queen Consort' would be very awkward.
Kate's sister will be their bridesmaid
No.
No, they are Anglican. Kate was born a Catholic but had to convert to the Church of England to marry William.
