I'm new to the batman comic books and starting at Batman: Year One. I'm looking to read them in somewhat chronological order. What is confusing the crap out of me is I see all of these story arcs,(which I some-what understand it from that point) and these lists of them in order. What I'm not comprehending is I finished year one, (loved it), but now I'm kinda told to go read Shaman, to follow it chronologically, but I also see that in issue number, from Year One #404-407, it also goes into Batman: The New Adventures #408, etc. Are these critical to follow? Or should I not waste my time with them and just follow the story arcs? Are these included in another arc later? I realize the issue numbers won't match correctly due to release dates, authors, etc, but I don't want to move ahead and miss apart of the story if that makes any sense. HELP!
