Firebug is also a great tool for Firefox. For some things (editing CSS) better than Web Developer. jboss-portal.sar\portal-core.war\themes is only one important thing. Also important for understanding are layouts: boss-portal.sar\portal-core.war\layouts | | For each layout there will be a subfolder with 2 JSPs: | index.jsp - layout in general | maximized.jsp - layout if one Portlet was maximized | | There you can see the parts of your Portal. For example you see divs for navigation and dashboard. Like already mentioned, with portal_style.css you can customize each "region" by your own.
