Michele,
Welcome to the DIS Camping Board.
I know there are better forums to get Run Disney info about here on the DIS but we campers tend to be a different, fun loving group.
For the 10K, just be at the computer ready to sign up at the hour registration opens. It will fill up quick. I remember running through Epcot in a race years ago and it is cool.
John is right that the Disney runs are addictive. I did my first in 2001 and after the kids have grown up, here I am doing it again (although slower this time). He seems to be the Yoda of our Camping Run Group. This is the ultimate "Destination Run" whether its the Marathon weekend or any of the other races sponsored during the year.
We will likely do a post-registration status check after April 26 to see what happened for everyone. Hope to see you there.

PS - have never done Pasta in the Parks. I'm usually trying to get to sleep early the night before a race (usually too excited and unsuccessful) so I am not a night owl. More of an early bird myself.
