Lionel:  Regarding the last point - there is an easy-to-use utility 
called shpproj that can convert shp files from projection to geographic 
coordinates (http://shapelib.maptools.org/shapelib-tools.html).  Once it 
is converted to geographic coordinates, you can use the Basemap to read 
the shapefile and plot the data.  The fillstates.py and hurrtracks.py 
examples show how to plot data from shapefiles.
