The datastore cache does not have to be set to xcache. That was only a recommendation.
The xcache admin user and pass must be set in config.php. Read the install instructions to see the code necessary to add to config.php to do this.
As for your question about a php handler, my mod does not care which you use, but xcache might need a specific handler - I'm not sure. You will have to ask google or look on the xcache website about installing xcache.
