Hello,  I recently decided to take the plunge into Blender and of all the tutorials I've seen, Blender Basics 3rd Edtion got me up and running pretty darn quick.   You can download the pdf here:

I found it to be VERY helpful.

Also, Over at the Silo 2 forum I participated in a little discussion on how to export Poser models and sculpt your morphs as a SINGLE mesh and then load the morph targets back into Poser as individual body parts.  The same concept should work with Blender.
