Hello Buddhfame - in order to learn about Buddhism from the zero level please make sure that you know the lifestory of Shakyamuni Buddha well from both the Theravadin and Mahayana perspectives. It is from this slightly differing views that threads can be found that help explain the evolution over time of all the Buddhist traditions.
One life story can be found here
and there are several others (I particularly like Thich Naht Hanh's "Old Path, White Clouds").
