-- Some responses said Dining plan might be free, how is this done?
Usually if you book your trip in the summer for Aug or Sep, they offer the dining plan for free. There's no guarantee they will do that next year, but it seems likely at this point. That doesn't really help you if you were planning to go before fall 08.
-- I think we are leaning towards the Port Orleans French Quarter and a full week, but because of cost we might go to POP. . whats the main difference?
The Value Resorts are kind of like a themed motel. It's somewhat bare-bones. There's fewer ammenities and no sit-down restaraunt. Just a food court. The moderate resorts will have more room, more ammenities, etc.
You will probably not be in your room very much. So I don't recommend over-spending on the room. Most people just sleep there and use the pool.
-- We currently have a Disney Visa (got it when we decided to go) how do the points work and what extra benefits can I expect?
You get 1 bonus point for every $100 you spend. Once you have enough points, you get them transferred to a card which you can use to buy Disney stuff. It's good at the parks or the Disney store. It has other uses, but I've never used any of them.
There are occassionally additional bonues. Discounts are listed at the Chase website. They usually aren't anything spectacular. Also, you can get a free picture with the characters at Epcot. I've never done it myself, but I've seen them and it is a nice souvenier.
-- I think we are going to try and do all the fireworks shows. . . and a nice dinner every night with them (whats the cost of the fireworks cruise). Where are some good places to eat?
I'm gonna let someone else help you out here. My wife is a light-weight and she never makes it to the fireworks.
Okay, a few tips because I can't help myself:
For Fantasmic, there is a dinner package(

At Epcot, I hear that outdoor seating at the Rose and Crown is ideal.
At the Magic Kingdom, I believe I have heard that California Grill is a great place to eat and watch the show.
-- What are EMH and how exactly do they work?

-- Anything else I should know??
Tons. Others have recommended buying a travel guide. I'd recommend buying one or getting one from the library. The Official Guide has lots of good pictures. I recommend it to first timers. However, the Unofficial Guide has more helpful information. Ideally, I'd flip through the official guide and then read the Unofficial Guide.
Supplement all that with on-line research and questions asked here.
