I would suggest this in order:

1. Figure out what you want to build

2. Read the getting started docs a bit

3. As you figure out which features you want, look up things on a need to know basis

And repeat that loop until your project is done.

As for learning material to help with step #3, assuming it's a web app, personally I found looking at the source code for https://github.com/thechangelog/changelog.com/ to be highly valuable. The Programming Phoenix 1.4 book is great too to fill in some gaps of a "self learner". Also Alchemist Camp is quite good for seeing how to do 1 specific thing or generally look for workflow / implementation ideas.
