What a great time to go - the parks will be decorating for Christmas. I would check the park calendar, but from what I can remember you should be nearing the end of Food & Wine at Epcot. You might want to steer clear of Epcot on weekend evenings as it gets very crowded for Food & Wine.
You might be able to get in on the first Mickey's Very Merry Christmas Party at Magic Kingdom. I'm almost certain you will be there for the first night the castle Christmas lights (Cinderella's Dream Lights I think it is called) are lit. There is a special ceremony the first night I believe. We were there until November 5th last year and I heard it happened on the 6th. You might also be able to see the Osborne family lights at DHS.
As I said we left on November 5th and were at the Grand Floridian Villas and they were putting up the gingerbread house in the lobby that day. The gingerbread houses at the resorts are supposed to be pretty neat.
That might also be Jersey Week (many New Jersey schools are on break for a teacher's convention). We were there last year for the beginning of Jersey Week and I didn't really notice it increased the crowds, but some people swear it does.
November 8th is also the RunDisney Wine & Dine Half Marathon. That might also affect crowds.
Hope that helps!
