Hi Ivana,
  The APBS plugin in VMD 1.8.5 has a number of improvements which
you probably want, so as Axel already suggested, upgrading may be a good
idea unless you need to run VMD 1.8.4 for some other reason. As far as
finding the binary goes, so long as the APBS binary is called "apbs" and
is in your path, VMD should be able to find it automatically, if now, you
can tell VMD where to find it manually. The APBS plugin web page has
links to the main APBS page which contains tutorials and documentation
that should address your questions about the various parameters that
affect the electrostatics calculation. The VMD plugin doesn't do anything
special there other than provide an easy-to-use interactive interface to
the same set of parameters that one would normally write in the APBS job
configuration file. Let us know if you need more help getting this working.
