This is about the best guide you're going to find:
http://docs.oracle.com/cd/E19253-01/819-5461/There is a lot of information out there in the ecosystem. Good on you for trying to learn it step by step.
There is support available on our IRC channel, that you may find a little more interactive than the forums, but ultimately we are not realistically able to provide training to people.
