Well I have had Bryce for years and am still a total newbie, having read the Real World book AND the manual several times each.

I would recommend reading the Real World book AT your computer, and using the manual to look up things you require more information or clarification on.

Spend a LOT of time learning the Deep Texture Editor. The DTE is a major key to understanding Bryce. I still don't quite grasp it. ;)
