Well, right now is the time to go if you want to stay at a Deluxe Resort. One of my sister's coworkers is going to WDW in November and her travel agent got her a rate of $119/night at AK Lodge. I don't know the details of the room, but I've never seen rates this cheap. We just got back from WDW, and a family we shared a table with at Mitsukoshi Teppanyaki got a standard view room at Grand Floridian for $149/night. At least right now, the deluxe resorts are a bargain -- in these some case not as bad as they used to be.
And I think if you eat wisely, the food prices really aren't that bad. We usually plan on a breakfast a "fast food" type breakfast, since you get similar food (eggs, pancakes, french toast, etc.) for about half what you'd pay at a sitdown place, then we pick a really nice sit down restaurant for either lunch or dinner. The other meal of the day is usually a snack somewhere.
Having just been to WDW for 10 days (8/16-8/25) we (just my husband and I, no kids) spent around $1500 on food, souveniers, DisneyQuest, two days of water park entries, one game of mini-golf and our rental car. We are DVC members so we got a discount on DisneyQuest, the waterparks and the mini-golf. We ate at fantastic restaurants (Wolfgang Puck's, Tony's for the Pooh character lunch, Ohana's, Cape May Cafe, Mitsukoshi Teppanyaki, Whispering Canyon Cafe, ESPN, Mythos at Island of Adventure, California Grill and Kona Cafe for Tonga Toast on our last morning). We ate whatever we wanted, had drinks at several meals (though we were too full for dessert a few times), and we blew $140 on dinner at California Grill, which was totally worth it. We didn't buy many expensive souveniers this time, though we did buy a painting of the beach at the Beach Club (which is where we got engaged) which cost us $100.
I hope this helps!
