I'd say epslatex.pdf is a good read for including graphics into .tex
files in general; the specifics about the EPS file format are not that
relevant anymore, probably.

Or you could simply hardcode the path to the file inside
\includegraphics for this kind of rather small documents.  Personally, I
think all this is relevant only if you're using the good old latex-dvips
route.  With the advent of pdflatex, you can plonk all your graphics
into a single file and then use the 'page=X' key-val inside the optional
arg of \includegraphics; then you can have your single file with the
graphics in the same directory of your main-file.tex and all the
path-searching stuff isn't really necessary.

See Keita's answer.
