Carlos, the best way to do what you want is to use OpenLayers.StyleMap. See http://trac.openlayers.org/wiki/Styles for a tutorial and http://www.openlayers.org/dev/examples/georss-flickr.html for an example. You could also use SLD to define your styles. In that case, look at http://www.openlayers.org/dev/examples/sld.html for an example.
Things get much easier if you apply http://trac.openlayers.org/attachment/ticket/1373/1373-r6361-A0.patch to the current trunk version of OpenLayers. This patch also contains an example which should do quite exactly what you need. Regards, Andreas.
