I am using MySQL at the moment, so I cannot really help you with the distance calculations, but the documentation at http://code.djangoproject.com/wiki/GeoDjangoDatabaseAPI#DistanceLookupssuggests that your distance calculations should work at least if your SRS is in meters/km etc.
I you mean default SRID as -1, I tend to think of it as a "don't know/don't" care in the DB, making it store the data but without ability to interpret it in any geographic way. I always store my geodata with a known SRS, be it 4326 (WGS84) or whatever the data came in. If you have a look at your data source with any kind of GIS software, it should tell you what SRS it is in. If you set it to -1, the DB will have no idea how to do the distance calculations.
