The answer to your questions, of course, depends on where you are going!
If you are going to MK, you can either take the boat or bus from VWL. You will be able to monorail to MK from whatever they end up calling the Contemporary.
If you're going to Epcot or Disney's Hollywood Studios, you can either boat or walk from either BWV or BCV. You could also walk to Epcot and monorail to MK...although that would be a bit of a trek.
If you're going to DTD, you can either boat or walk from SSR or OKW (although few would walk from OKW).
