Read this before Posting PDF Questions  There are some good tips in there.
Anyways, I converted your PDF to PRC (forerunner of MOBI) with Mobipocket Creator (Windows proggie) and converted that to EPUB with calibre, using stock configs in both.  Results attached
I convert upwards of 10 simple PDFs a day via this method.  It's not One-Click but it's consistent at getting the job done, and the XHTML/CSS code is good enough for me.
