Are there any plans on ordering a set of questions to be printed out and delivered in book format such as wikipedia has planned to do?
Your prayers have been answered long ago: http://www.stackprinter.com/
http://www.stackprinter.com/export?question=2836&service=meta.aviation.stackexchange [1]
You can use the site to print the questions one by one into PDF files and then merge the files into a booklet.

The Stack Exchange network licenses user submissions under CC:BY-SA 3.0 [1] though, so as long as you properly attribute [2] each post you're putting in your collection there doesn't appear to be anything else standing in the way of such a project.
Organizing such a book would be a significant challenge - even the taxonomy of tags doesn't really do a good job of putting questions/answers into useful, indexable categories (at least IMHO).
