O.K., I've not seen those.
My sources are
1) AWDWR,
2) Railscasts http://railscasts.com
3) Rails docs http://api.rubyonrails.org/
4) Programming Ruby http://pragprog.com/book/ruby3/programming-ruby-1-9
5) The log files 
- learning how to read your log files is the biggest help you will get.
5) Stack Overflow.
Best piece of advice I can give you, don;t fight it! It's too temptiong to do things your way rather than the Rails way. If you learn what Rails expects you to be doing it's a breeze 
, a common truism in the Rails world is "If you are finding it difficult, you are doing it wrong"
My light bulb moments were
1) Forms - Realising that forms (form_for ... |f|, form_tag etc...) are rails way of defining the url that a form is posted back to and the stuff that gets attached to the form (f.something) is Rails way of conveniently defining the parameters that get passed back to a controllers action in the params hash
2) The log files are your friend.
3) accepts_nested_attributes and fields_for for capturing data for more than one table (model) at a time.
accepts_nested attributes means exactly that! Defining accepts_nested_attributes for model_2 in model_1 class means that params hash attributes for model 2 that are nested inside the params hash for model_1 (by using fields_for in yout view layer) will automatically cause model_1 to update or create the associated records for model 2
4) Rails is a 3 tier system where the views and controllers form the first tier containing all the view logic, models form the 2nd tier containing all the the business logic with the database obviously being the 3rd tier.
5) When starting out I felt that I wanted to get to the point of "hand crafting" rather than generating my models, controllers etc... when actually hand crafting gives you 10 times the amount of work to do
6) Testing is easy and essential as Ruby is an interpreted language not compiled. AWDWR deals with testing extremely well but I also foun this railscast to be totally inspirational http://railscasts.com/episodes/275-how-i-test
Good luck and welcome to the world of rails
What you want and what you need are too often not the same thing!
When your head is hurting from trying to solve a problem, stop standing on it. When you are the right way up you will see the problem differently and you just might find the solution.
