I downloaded the PDF and something's totally wrong with the font -- it doesn't display characters at all. Just line graphics where the words are. Even if you fix the font, it would suck because of the margins.
Your best bet is to convert it to text and/or heavily edit it with something like "Book Designer" covered elsewhere in this forum. I'm a total novice with BD but I imported your PDF and it must have some funky tags in it because it comes up butchered.
I tried saving it as a DOC file from Acrobat 7.0 (usually works pretty darn well) and it butchered it totally. Sideways pages, weird fonts, corrupted formatting.
This PDF is really, really funky. Sorry I can't be more specific but I'm at the limit of my PDF knowledge.
