We current distribute (all PDFs)

 - expl3
 - l3style-guide
 - interface3
 - source3 (might currently be missing!)

I'd start with expl3: it's an overview of the ideas. The style guide
document is as you'd expect a guide to help programmes. The main ref. is
interface3: it's not really a guide, more of a reference work. Other
than the kernel team, I'd hope no-one really needs to print off and read
source3!

For learning to use expl3, we currently don't have a 'complete' guide.
I've posted a series of articles on my blog that are meant to partially
address this:
http://www.texdev.net/2014/02/02/programming-latex3-a-summary-so-far/.

We (the team) know that there is a book in development as a proper aid
to help new expl3 programmers. However, at the moment I don't think
there is an ETA on it.
