I worked at WDW for two months in their college program, so I maybe able to assist you with any questions you may have.
Firstly, Wilderness Lodge from all accounts is excellent.
As for the parks, if you have already bought a park hopper(which I think you have) then you should see all of them as you have already paid for it. Since you have 5 days my suggested viewing order is
Day 1: Magic Kingdom - Whole Day (including Wishes fireworks at Night) The fireworks is not to be missed, its exactly like the photo you have put up in your post. Usually its at 8pm but later on Saturdays. Rides not to be missed at MK
include Space Mountain, Big Thunder Mountain, Splash Mountain (it should have re-opened by then). Good Dining places at MK
include the Plaza, Liberty Tree Tavern and Cinderella's Royal Table. Avoid Crystal Palace, the food is average. Also if you wish to see the Dreams Come True Parade, the best place to see it is at Frontier Land near Splash Mountain. The Parade begins here and you will usually not have to find a spot an hour in advance to view it.
Day 2: EPCOT - Rides not to be missed are Soarin, Mission Space and Test Track. You can ignore Spaceship Earth if you like. But EPCOT is really more about the World Pavillions and for the most part they are really nice. Shows not to be missed are the shows at Morrocan Pavillion, the Drum show in Japan, the show by Children just outside Chinese Pavillion and O' Canada. For lunch I would recommend the Cafe (not the restaurant) at the Morroccan Pavillion and for dinner The Nine Dragons at the Chinese Pavillion. Also not to be missed is Illuminations at 9 pm. This is a fireworks/lightshow that is held over the man made lake.
Day 3: Morning: Disney's Hollywood Studios (previously known as MGM Studios) - Great rides include Rockin Roller Coaster by Aerosmith and Tower of Terror. Shows not to be missed are the Car Show (I think its called Indy Speedway - cant remember) and the Indiana Jones show. Watch Fantasmic before you leave this park. Its a Disney wonder.
Evening: Head to Downtown Disney for shopping at the World of Disney Store. Other major shops include Virgin Megastore, Ghirardelli, Planet Hollywood, Art of Disney and Lego. For dinner I recommend Rainforest Cafe. After dinner watch La Nouba at Cirque du Soleil. I found the show to be absolutely fantastic. If you want to go clubbing after that check out House of Blues (great on a Sunday night as all Disney College Program cast members are there) or 8TRAX.
Day 4: Morning: Animal Kingdom - Well pretty much only because you paid for all the parks. The only decent rides are Everest and Dinoland. Kali River Rapids is also good but too short in my opinion. See Finding Nemo show and goto Kilimanjaro Safari. Lunch at Yak and Yeti.
Evening: Go to Downtown Disney again and take a cab to Orlando Premium Outlets. Factory outlets for many brand names at fantastic prices. This is where I spent the bulk of my paychecks. You could have dinner on International Drive which has many restaurants or if you have paid for ALL
your meals then I recommend having dinner at Disney's Polynesian Resort.
Day 5: Well you could either see any of the parks that you have liked the most or go shopping. Or if you are a roller coaster fan I suggest making a day trip to Busch Gardens at Tampa, which have fantastic roller coasters.
Transportation Tip: Disney runs free buses from all resorts to all parks and Downtown Disney. However, buses do not run directly from ANY theme park to Downtown Disney ( I dont know why). To go to Downtown Disney from a theme park you have to take a bus from any one of the resorts. Not necessarily yours.
If you have any further questions or clarifications do ask. And have a great trip. Its a fantastic place.
