I'ma gonna agree with r3x.
Marvel's events tend to be contained within the parent title or mini series. Dissassembled, for example, was only in Avengers. There were tie ins, yes, but they weren't necessary to the story. You can read the Dissassembled TPB and get the story, from beginning to end (which I did, and enjoyed). You don't have to read the peripheral stuff unless you feel like exploring the idea a bit more.
DC put shit in some titles that directly affects other (did Wonder Woman kill Lord in her title, Superman, one of the minis or a secret files or what? I actually forget).
