Mark, Coloring by partial charge should work fine, provided that you supply partial charges to PyMOL...which isn't trivial. You could either assign them using the 'alter' command after loading a PDB or SDF file, or you could convert your molecule into a Chemical Python "model" object, assign them via Python, and then load the model back into PyMOL.
Coloring by electrostatic potential is something I am hoping to get into version 1.0...but PyMOL's current support for it is weak to non-existent.
