Hah!

No such thing exists...period.  None of the books, manuals, forums, blogs, websites, stone tablets or cave paintings are in any way complete and comprehensive.  They all make huge leaps of assumed knowledge and/or leave out minor but essential points.  

All this being said, all the  necessary  information is available...somewhere.  If you put all the video tutorials together and read all the books,blogs, etc you'll eventually learn all the skills required to make stuff for Poser and Daz.  I've been on this journey for a year now and have learned a lot but it hasn't been easy.  The 'official' manual that ships with Poser glosses over much of the material leaving one scratching one's head.  I bought two actual books that filled in a few gaps but...        I've downloaded every single tutorial from YouTube and even bought a few instructional video sets.   It's hard to find a guide to the basics of Poser since they all assume you know it but....

A great place to start is here (  http://drgeep.com/ ).  The 'doc' lays the foundation with comprehensive instructions on the basics.
