The "Nook Simple Touch" also has a resolution of 600x800, so it probably doesn't look very good on it either.
Source looks very good except that, well, you're trying to convert a PDF to a PDF... And that's very bad. PDF is meant as a final destination. For a proper conversion, you would need the original Word/OpenOffice/LibreOffice document (or whatever the author used), but then again, the equations aren't helping either - they will need to be converted to GIF/PNG, because Kindles don't do SVG. The rest of the images should be kept as colour images, in case someone reads it on a Kindle Fire, not automatically converted to 1 bit images (black).
Heh. If you were hoping for a one click conversion solution, there is none. Personally, I would extract the text with ABBYY FineReader, proofread it, save as RTF, run a custom Word macro that gets rid of the styles (but keeps italics, bolds, superscripts, places the footnotes as inline text, etc), import into InDesign, redo the layout, save it as an ePub, convert the ePub to Mobi, then proofread the final product and adjust as necessary if something doesn't look right.
