Good list, but they left off one of my favorite examples- James Avery, who played Will Smith's uncle in Fresh Prince of Bel Air, was also the voice of the Shredder from TMNT.
I might recommend Catherine Ndereba, the first woman to win the Boston Marathon four times, and former world record holder. I went out to the Chicago Marathon when my step-father was running in it, and saw Ndereba set the record, so I'm a little partial. Good luck in your 20K!
I think JoannaL has hit on an interesting direction- what would be the most useful invention or scientific information we could relay (in pretty limited space) for the benefit of future civilization? I think there was a bit in the Feynman lectures on physics where he claimed the most important piece of information was the matter is made of atoms, and this could set people on the right track towards rediscovering much of chemistry and physics, should it ever be lost.
Of course, in the more philsophical vein, we should also remind everyone to "Be excellent to each other. And party on, dudes!"
