The U.S. Bishops seem to be on top of things with the death of Pope John Paul II. They have several resources available on the web including overviews of the Papal transition process, and information on the College of Cardinals.
They also have several documents on those he canonized, beatified, his travels, major writings, a gallery of hi-resolution photos, and a biography of his life.
Their servers seem to be running a bit slow, presumably due to heavy traffic, but if you are patient you should be able to get through.
