General: Audit Dimension

What is the best practice for setting up audit dimensions in 2005? I know that we have the audit transform available, but should we be capturing extra information beyond this?



I had seen one of the design tip articles by kimball on what should be added, however, this article was from some time ago... (http://kimballgroup.com/html/designtipsPDF/DesignTips2001/KimballDT26AddingAnAudit.pdf)



Also, I try to capture the audit guid in the record and then, later, capture the rest of the audit information... I notice that the guid's are different between the audit transforms... is there a way to capture all of the information but not write it all out to each record? i.e. only capture the guid to the record and the rest of the information to the audit table.
