Chk,
The single most important piece of information, how experienced and strong you are wasn't provided. It's difficult to recommend a general method of training to someone who is directly under my tutelage. Offering advice to you based on just the information you gave could be counterproductive.
What are your goals in learning these openings? That is, once you've learned them, what will you gain by knowing them? Are you going to be using them in top-flight tournaments, local weekenders, hustling games in the park, beating your dad/son?
Do you have an official rating somewhere, and what is it? Are you currently playing tournament chess? How long have you been playing? What methods have you tried in the past to help you learn the openings, and to what extent were they useful?
I know these are a lot of questions. But just to give two extreme examples, I would (after the shock and horror, not to mention the honor of being asked
) give completely different advice to Anand than to someone who's about to enter his or her first school-wide tournament.
