The thread you posted looks a little busy so I will try to get you some info here. If the thread has gone too far off topic it may be best to start a new thread and just reference anything that you need to.
The idea is like this, when a user logs in you can store any value from that users record in a session variable with Security Assist. It is common to store the id in a session variable. Assuming that your login is setup like this you can retrieve any info about that user on any page by using the session variable.
With the userID session variable present on any page you would like to get the details for that user you would just create a recordset in Dreamweaver. In this recordset just choose the user's table and all the column. In the filter section you will just specify to filter on the userID column, with a session variable, then enter the name of your session variable that holds the userID. If you need to look it up you can find it in the authenticate user server behavior on the user login page.
