Well this is kinda hard to elaborate on at the moment since this is what I am working on at this very moment and Im not quite sure of all of the changes that I need to make.  Right now I think it should just be the buildQueryString method.  All queries *should* be abstracted to the Solr class to allow for backend portability.

Yes - everything from the PHP importer is in the Java importer.  I'm also adding some new fields and they will be added to the new java importer - not the php importer.  We hope to have a configurable map file for the 1.0 release.  Does this answer your question?

Just the weighting - since we are using defined fields in the schema, all that could be configurable is the weighting.  Changing the fields would be a very difficult task since the fields are used throughout vufind.  But is something that could be investigated.  The Blacklight project uses only dynamic fields.
