Using VBScript - How to retrieve SI_USERGROUPS, SI_LASTLOGONTIME, SI_DISABLED & SI_FORCE_PASSWORD_CHANGE

I'm trying to retrieve these SI_USERGROUPS, SI_DISABLED, SI_FORCE_PASSWORD_CHANGE, SI_LASTLOGONTIME, fields along with the rest of the other fields in below query with VBScript so that I can create a .CSV flat file output containing each user information along with each group s/he belonged to (one line per group). So far no such luck. Since I'm not very good with all the object's Properties stuff any help or pointer will be greatly appreciate it. 

Set myUsers = iStore.Query("SELECT TOP 1000000 SI_NAME, SI_USERFULLNAME, SI_EMAIL_ADDRESS, SI_USERGROUPS, SI_ALIASES, SI_FORCE_PASSWORD_CHANGE, SI_DESCRIPTION, SI_LASTLOGONTIME, SI_CREATION_TIME, SI_PASSWORDEXPIRE FROM CI_SYSTEMOBJECTS Where SI_KIND='User' and SI_USERFULLNAME != '' ")

In the For... Next loop, I can get three fields but the rest have no clues.

For Each UserItem In myUsers

     UserItem.Title    

     UserItem.FullName

     UserItem.EmailAddress

     UserItem.??? for Group(s)

     UserItem.??? for Disabled

     UserItem.??? for Force password change or never login

     UserItem.??? for Last Logon Time

     UserItem.??? for Create Date

Next

Secondly, where can I find the information about the rest of the Properties for such UserItem.??? above? In another word, how do I know that UserItem.Title is pseudo name for SI_NAME and so on?

Thank you in advance for your help.
