 Boas

A vantagem do firebug eh que podes ver as variaveis e tudo o que tem
dentro, alem disso acho bastante util as funcionalidades NET em que ves
os pedidos feito pelo codigo, do genero ficheiros descarregados ou
pedidos de capas.

Por exemplo, se metes no teu codigo: console.log(wms_ruas) podes ver o
object wms_ruas e tudo o que ele tem dentro.

Se so tens wms_ruas como layer teras de meter isBaseLayer:true  acho que
se so tens uma layer e ela nao e' considerada baseLayer entao o
openlayers nao mostra nada ( alguem pode confirma lo que dice !? Nao
tenho muita certeza)

Tb convem adicional o atributo strategies, experimenta o seguinte:


  var wms_ruas = new OpenLayers.Layer.WMS(
           "ruas",
           "http://localhost:8080/geoserver/wms",
           {'layers': 'postgis:ruas', 'format':'image/png',
'transparent':'true',strategies:[new OpenLayers.Strategy.Fixed()]},
           {'opacity': 1.0, 'isBaseLayer': true, 'visibility': true}
      );
