Since one is indeed very Qualified and virtuous, he/she knows what we need as help at all the stages of our preparation, like a father figure. I therefore, urge all of u to not waste time and to get started with ur respective preparation.
A relevant book, is the only thing that might be preventing you from going in depth with your preparation.
I myself, feel it would be ideal to start with the Wikipedia and the Net to get to the appropriate links that will introduce u to the topic and in the meanwhile if u get the ebook or be able to get the conventional textbook at a library or somewhere u can get started with solving the questions, asap, after the theory is sorted out and well understood.
