Yes sorry for the confusion, I am quite frustrated as I have been doing many
investigation till now and I haven't found a solution.
Well, by "bad" I meant mainly the quality of the image but I was wrong
because that is the nature of the shape files although the way.shp is
actually incomplete ( I created with ogr2ogr.exe ), but it doesn't matter,
the shape files are only an experiment, at this stage, for me, you are right
I should test on Linux maybe with osm2shp as suggested elsewhere. Problem
for me is I don't know Linux, but I'll have a go at some point of my
investigations.

What is more needed for me now actually are raster data which don't loose
quality when the user zoom in. I tried creating an SVG file with xmlstarlet
and converting finally into a TIF/TIFF file and it is perfect but when you
zoom in the quality is very get worse and worse.

The point is I'd like to host the OSM data instead of using the "tah" server
but I can't find an easy way with an accettable quality. 
I understood I should download the tiles for different zooming levels and
implement somehow myself a cache / tiles web engine, correct?

I think OpenLayers people have done it already but I can't find any
documentation for doing it myself.

Cheers,
Rosario
