Well, that is a very open ended question. I'm not sure what you don't already know. Do you have any specific questions?

Be sure to read the stickies at the top of the page. Lots of good info there.
You can look for the light on in Walt's apartment over the firehouse.
The monorail isn't really a transportation like at WDW, but considered more of ride.
Get FPs for Indy and Space first thing in the morning. Indy seems to be breaking more often these days, so don't save it for last if you really want to ride it, just in case.
I would imagine that you would bring the same things here that you would in WDW. Like baggies, hand sanitizer, water bottle, sunscreen, etc.
I like Whitewater Snacks in the GCH for lunch. It is easy to get to from DCA and is quiet and uncrowded and has good food.
