There are many threads on here about the order to attack EE. Generally, it looks like this:
Peter Pan
Dumbo
Alice
Matterhorn
Teacups
Toad
Pinocchio
Snow White
Buzz/Space
OR
NEMO (if you choose to do Nemo during EE, plan on it taking the entire hour and if you have extra time, hit Buzz or Space afterward)
Fantasmic: Try to go to the second show if there are two. If you can plan to be in NOS doing rides while the first show is running, you can just move in after the first show crowd gets up to leave, and it's pretty easy to grab a great seat.
Fireworks: Believe wll be showing when you are there, so you should try to get a spot on Main Street somewhere between the Candy Store and Coke Corner in order to get the best view of the fireworks and enjoy the snow.
HTH.
