Anisha, I think you need to move a bit slower :) Take some time to understand that data is in different map projections [1] and you can't just switch out data exported from postgres (that I assume is in EPSG: 900913) with a shapefile that works with a tutorial that is in EPSG: 4326, without also modifying the XML 'srs' parameter. See http://trac.mapnik.org/wiki/IntroductionToGIS for more details. I might recommend to you to check out QuantumGIS. http://qgis.org. QGIS provides an interface to allow you to load up different data, and does a descent job of automatically interpreting the projection (Although note that is does not understand EPSG:900913).
