A good way to supplement that, among others, is to read the critiquing of dissenters written works. I have found that when someone - priest or lay person, who is solid in his understanding of catechesis and theology, publicly examines the words of dissenting priests and theologians, there are many things to learn. It will get you thinking.
Fr. Z has a piece up in which he critiques an article by dissident Hans Kung. In order to understand common errors circulating about Catholicism today, I would encourage you to read Fr. Z's take on the article.
