A good starting point would be the "Administrator documentation" http://docs.moodle.org/en/Administrator_documentation

There is also a Moodle Partner in India: http://moodle.com/partners/list/#India and the book 'Moodle Administration' by Alex Buchner http://moodle.org/mod/data/view.php?d=55&rid=1942

I'd recommend a project-based approach.

You should also set up a Moodle site (using the docs if necessary), think of a real application for Moodle (eg a University or a school) and then try to set up Moodle for that situation). It doesn't have to be a real school, but obviously if it is then you have more motivation

This process will generate questions whenever you get stuck. You can then search for the answers to these questions using the resources here: http://moodle.org/support/

1. There's also the "Moodle Administration" chapter in Using Moodle, which will explain the uses of the Administration block.
2. We used Martin's idea of project based learning. For example, I had someone else designing quiz questions for a grammar course. Our purpose was to reduce the amount of bookkeeping that instructors had been doing.
   She would send me the questions, and I would investigate how to make them work in Quiz. I would have her look at how I'd implemented the questions, and she would comment back on whether the implementation made sense in the context of the curriculum. I would try a different approach, she would comment, etc. In this way, we learned Quiz.
   In a similar way, we learned Lesson and which kind of Assignment to use (we're firmly in favor of Advanced Uploading of Assignments).
3. If you have worked with another cms/lms/vle, Moodle's standard parts will be familiar to you, but the hardest part of changing cmses is to quit thinking in terms of the old cms and let Moodle tell/show you what you can do better.
