Ok, although EPSG:4326 is the default so you do not need to set it.

Don't add REQUEST and SRS params -- OpenLayers will do that for you. But
make sure to add a LAYERS param.

You have to zoom to an extent first to see something:

map.zoomToMaxExtent();

Also look at one of the examples (e.g.
http://openlayers.org/dev/examples/lite.html) to see how this works.

Extent() is not a method of the map, so what you are trying to do here
cannot work.

map.Extent() will raise an exception. Did you mean map.getExtent()?
