   That is correct.  If you saw a red 'X' over the icon next to " PostgreSQL
Database Server 8.2 (localhost:5432)" then the server would be offline.

   Nothing :)  A server (aka database cluster) can be started or stopped.
Once started, a database server has multiple databases that you can connect
to within it.  If you drill-down beyond the 'postgres' database, you will
see 'schemas'.  Drill down further and you will see 'tables' etc...

  The username / password will not be the same as your windows logon.  It
will be the postgres database username / password.

   Try the username 'postgres' when connecting to another server.

 To be honest though, I don't think you need to do this, it sounds like you
just need to drill further into the 'postgres' database in the tree.

 That is a user that was created in the operating system.

  Postgres has 2 types of users:

  *) OS user
     There is only one of these (in your case).  When postgres starts (look
at the services control panel) it uses that windows logon to run the
service.  Postgres cannot be run as a 'root' or 'admin' user for security
reasons, so the installer creates a user for you.

*) Database users
   These are users inside the database cluster that have privileges on each
table / object within the database.  These users can be named the same as OS
users, but for all intensive purposes, are in no way releated to windows

  I'm not really sure you have a problem, just spend some more time clicking
'+' signs in pgAdmin :)
