org/apache/solr/util/plugin/SolrCoreAware in the stack trace refers to an interface in the main Solr jar.
I think this means that putting all of the libs in apache-tomcat-6.0.20/lib is a mistake: the classloader finds ExtractingRequestHandler in apache-tomcat-6.0.20/lib/apache-solr-cell-1.4.1-dev.jar, but that it wants the above interface. The main Solr jar is not available somehow. Since the solr-cell jar is in multiple places, we don't know exactly how Tomcat finds it. I suggest that you go back to a clean, empty Tomcat, and the original Solr distribution. Copy the solr war file to the right directory in Tomcat. Get Solr talking to your solr/ directory (-Dsolr.solr.home=path). Now, check if the <lib> directives in the solrconfig.xml are right.
