I'm hoping you got this solved already, but if not...
You can download the metadata file from http:///your.domain.here/Shibboleth.sso/Metadata
You can test your Shibboleth setup using .../Shibboleth.sso/Login and ../Session and .../Logout
Those entries would be provided by the Apache SP2 module, assuming you're using apache.
We're in the process of setting up shibboleth and I found http://www.jeesty.com/shibboleth helpful
