Answers.Text: The third option worked, I sent the document to my kindle email with the subject "convert" and it converted the document. Note though that this feature gives no special consideration to code blocks within the document resulting in "less-optimal" code format, but could live with it. So, thanks.

  This is really the nature of the beast. PDF is a rendered format, so is MOBI. Converting from one rendered format to another is going to introduce these imperfections.
  
  As I see it, you have two options: 1)convert the PDF to MS WORD (and fix all the formatting errors), then run it through Calibre and 2)read it only in a PDF reader on a mobile device.
  
  Actually there is another option: use Amazon's Personal Docs/Content server (which will convert automatically from PDF to its mobi format). <https://www.amazon.com/gp/help/customer/display.html/ref=hp_pdoc_main_short_us?nodeId=200767340> I have no idea whether Amazon's conversions are any better than Calibre; probably not, but it's worth a shot.
  
  MS Word poses other conversion challenges, but at least it's something which can be processed more easily than PDF.
