What do you prioritize and MAKE SURE that you get to see while there?
1. The British Museum
To be that close to the Elgin Marbles and the Rosetta Stone and not see them would be criminal.
2. Westminster Abbey
A close third behind those two would be St. Paul's Cathedral--I actually like that one more than WA but the historical significance of the Abbey elevates it on a first timer's list. If you go, pay the money to climb to the upper Galleries--the view from the Golden Gallery can't be beat.
You can do those three in a day if you just want to hit the highlights of the British Museum.
After that it's up to your interests. Personally I would go to the National Gallery, the Tate Modern and spend more time at the British Museum if I had just three days. The Tower is a very good choice, but it is a bit out of the way and will take you the better part of a day if you see everything there. Greenwich (Observatory and naval museum) is a bit farther out of the way but also a great choice if you have an interest in the history of the 1700s-1800s.
Whatever you do, don't waste your bloody time watching the changing of the guard.
