:p
Granted, some info would be nice for new users.
Figuring it out is easier than figuring out the sql DB itself.  but you can get a lot more out of knowing the DB...  Besides, the admin tool is broken due to the latest patch.  Edit ok, new admin tool is out :p   Go Windcatcher!
It also depends on what is considered good documentation, All the info you need is there or in the eqemu source 

  you just want it written a different way. Bottom line is the DB isn't simple, you really NEEd to figure a few things out.
