Only overwrite the jar's if you use Solr 3.x branch or trunk. If you're using 1.3 or 1.4.1 then you're fine with the jar's that come with Nutch 1.2.
The schema.xml and solrmapping.xml files are just examples that come with Nutch. Nutch won't index your Solr database, it will only send data to your Solr index using the solrmapping.xml as a mapping between Nutch' fields and Solr's fields. You need the solrmapping.xml in your Nutch configuration and schema.xml in your Solr configuration, then you're good to go with an example crawl. Fire the solrindex command and if it fails, send output from Nutch' logs/hadoop.log and the output of your Solr servlet container.
