I need help with the base tables so I can document my installation

1) I need a query that will list Support groups with all technicians in it.

2) users with within each user group

3) Support Group attached to each incident template

4) Group attached to each service catalog template.

 

Given the time I could find these Im sure, but I'm just not familiar enough with nor have the time to dig into the database schema to find these answers. If anyone has the table and joins for these types of reports, I'd really appreciate some help.
