A good point to start is maybe to look at Learner's APBS plugin. Also there
should be some documentation about the ?OpenDX? format apbs is using for
potential maps. It has also isosurface display controls implemented.

Sign information? If you're talking about a simple scalar potential, i see no
problems arise. The probability amplitude should be always positive or what
do you mean?

There are 2 things you can do IMHO. Either creating isosurfaces with fixed
color or color sth else e.g. the sas surface of a protein with the potential
values.
