Hi,
I am a BScEE with 5+ years of experience in software development and I would like to help you with this; I have developed backbone-based framework for the company I work with, with quite a bit of proprietary automatization features (integrated server-client validation, automatic model extraction etc), so I know the backbone internals really well.
Backbone literature is sparse (don't know of any resource worth mentioning, except of that Addy Osmani book and source code itself) and its event-driven architecture makes it hard to debug, so being familiar with its source code for anything but basic purposes is a must in my opinion.
What other backbone-related components are you using, do you have your own or you use some of the open source validation & model-binding libraries or any backbone-wrapping APIs such as Marionette?
Kind Regards,
Vladan Stojanovic
