I think basically you can have only two different things in a printable 
PDF file from TeX: text and graphics. Text needs a font, so make sure 
you're using only vector based fonts, i.e. PostScript, TrueType, 
OpenType, *no* PK. This should work, since I all more or less usual TeX 
fonts (Computer Modern, Concrete. AMS, ...) are meanwhile available as 
PostScript fonts. But look nevertheless into the log file: footnotes, 
footnote marks, captions are usually (?) set in a different TeX then 
the one(s) you choose for the main text with a \usepackage{times, ...} 
or such.

If you use graphics to explain things, try to use pstricks. PS is 
vector based and renders in any resolution. I think this quality is 
saved too when you have EPS without bitmapped graphic content that you 
need to convert to PDF -- but here I am not completely sure. If you 
have other graphics you should try to convert it to PostScript or PDF. 
Screenshots at 72 DPI probably can be 'enhanced' to not look like LEGO 
at 2.400 DPI, but probably this work will take a long weekend, possibly 
for each screenshot.

Look at your graphics at 3.000 % magnification -- that's close to from 
72 DPI -> 2.400 DPI.
