The information collected during authentication would be:

asserted identity url
signature generated by the identity server
connection information (ip addresses involved, etc)
http headers

Am i missing anything?

Other than the asserted identity url (which should probably be assumed 
public), the other stuff probably fits into the shady netherworld of your 
privacy policy.

I would likely retain the same information that you retain for traditional
authentication on your site.  Being able to give useful information to the 
id server in case of abuse is nice though.  Having some sort of reputation 
service sounds scary, but would probably be useful.
