To import your own .osm file you'll need osm2pgsql in append mode 
(specify --append on the command line).

To add your own rendering rules, look at the osm.xml after running 
generate_xml.py. It includes a whole set of other styles (located in the 
inc/ directory). You can include your own styles that way, too (or, if 
you're in a hurry, just copy'n'past your own styles into osm.xml).

But there's a third way: you could render your own .osm with your own 
style to a transparent tile (like [1] which is used in [2]), fetch the 
base-map tile from tile.osm.org and combine both using the ImageMagick 
composite command [3].
