Thanks. I have been looking online and found those mentioned.Having a "good" book though saves all that printing and what really helps are people who know how to distill it down to important concepts. Somethings I run into I can't be sure if it's me or a bug etc... Just really getting a handle on the interface is what I am after now. The wiki was the most recent and it does seem better. I have not been getting expected render results for example with yafray even w/ plugin so wondering if it was me. Very exciting to see what is being worked on.

No need to think outside the box....
