Yes, you need to create both a QParserPlugin and a QParser implementation.
Look at Solr's own source code for the LuceneQParserPlugin/LuceneQParser and
built it like that.
Baking the surround query parser into Solr out of the box would be a useful
contribution, so if you care to give it a little bit of polish/unit testing and
submit a patch, the community would be thankful :)
