Hi

	I ran into some similar troubles when trying to incorporate  
Mathematica-generates EPS figures in TeX documents.  The problem is
with the bounding   box that Mathematica creates.

	At first, I wrote some Python code to fix the trouble (included  
below, no guarantees), but later I discovered the easiest way to deal
with   the problem was to copy the figure to the clipboard, paste it in
my word   processor (which fixed the BB for some reason), and save it
from there.  You   might want to try something similarly low-tech.
