Thanks everybody I'll try to follow the mapnik guide as Richard suggested.
Anyway I am already at this stage, I'll try next one.

I'll have a go with this one. I need to spend some time to learn at least
the basic of Linux first.
But just few questions before to start:
* How to define the table schema on PostGIS and does osm2pgsql already know
the db schema?
* Does mapnik reads directly PostGIS or reads images generated from the db
by generate_image.py?
* Reading the Martijn post seems this model doesn't cache data, right? Is it
the next step C) that does it, correct?

Sorry maybe too many questions but believe me I tried too at the minimum.
  
Cheers
