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. -- Joseph Wright
