Hey shabda, nice work. I have been following your blog posts to learn django as well. They are great resource for django noobs. The initial chapters of this book pretty look good.
It looks very promising. One thing that I think is often neglected is how to properly modify the admin interface to make it useful for all the little things you want to do. The admin interface is really useful and helps you get started fast, but it's a lot harder to grok and modify than models, forms and "vanilla" objects.
