F&W is the Food and Wine Fest. at EPCOT. It begins in the beginning of October and ends mid-November. There is a sticky at the top of the forum with a lot of the information.
As for your other questions:
What time do you arrive to WDW? Are you flying or driving? You just might want to be careful about having an ADR for a meal that you may be charged for if you don't cancel in time incase something happens that keeps you from getting there in time. So, for example, if your plane is scheduled to land at, say, 2:30 or 3, you might want to reconsider MBYBBQ on oyur arrival day, just in case.
Cape May is a pretty good seafood buffet but we have not tried Garden Grove so I cannot give any input on that. CR has fallen from a must do and a childhood favorite to a restaurant we will not return to anytime soon.
Are you on a dining plan or paying OOP? If you are OOP buffets are awfully expensive and are not worth the price you have to pay, but are good deals on a
DDP. If you are interested in buffets, Biergarten in EPCOT and Boma at AKL are both pretty good. The breakfast buffets are all pretty standard and will mostly depend on what characters you want to see if those interest you.
Some other 1 TS restaurants that are pretty good are 50's PTC or Sci-Fi at DHS, Sanaa @ Kidani, Les Chef's at EPCOT, RR at DTD or LTT @ MK. That should get you started with some ideas. Check the menus at allears.net to get an idea of what each restaurant serves (but note that the menus do change).
