Welcome, and here's a link to a Pop Century picture thread to get you started:

Here's a link to the Budget Board, since you've expressed an interest in that as well:
http://www.disboards.com/forumdisplay.php?f=22
I'd suggest taking some serious computer time to explore the various forums here on the disboards. In addition to the budget board for money-saving ideas, there is a restaurants board to help you figure out where you want to eat, and a theme parks board for touring strategies. Etc., etc., etc.
I would also strongly recommend that you purchase either or both of Tour Guide Mike (
www.tourguidemike.com) or the Unofficial Guide to Walt Disney World. TGM is a disboards sponsor who has an Internet-based guide to WDW that includes strategies for maximizing your time in WDW. The UG is a book with an affiliated website; they've developed touring plans that many people use to tour the parks efficiently. Both guides have lots of information about hotels (on and off-site), restaurants, attractions, shows, etc.
Now is not too early to start your planning, and for many of us the planning is half of the fun.
