Welcome to the forum, i'm new here too - so don't expect any fab answers from me.
I have no idea what pgp is, anyone else?
You'll have to contact your admin for database names, passwords etc, depends what type of hosting you have. But without knowing where your database is or the password you're not going to be learning a great deal (other than the importance of keeping important information in a safe an secure location).
Let us know how you get on -
