Using Pellet with Jena is covered in the FAQ at [1].  Further examples
exist in the Pellet distribution (see the examples directory).  If you
create a Pellet backed OntModel, using listStatements [2] will give you
asserted + inferred statements, an could be used to produce your
"modified by rule" ontology. (In Pellet 1.5.0 and previous releases
listStatements is incomplete.  This bug has been fixed for the
soon-to-appear 1.5.1).

For free, the Protege SWRLTab [3] may satisfy your needs. I believe
TopBraid Composer (which is non-free software) also provides some SWRL
visualization.
