If you read Bendis' stuff, you'll definitely want to read Brubaker's stuff which follows it. Then, Shadowland. Then, Waid.
Honestly, it's all pretty great from Bendis on. You're in for a ride.
With comic books, just remember: Wikipedia is your friend when something comes up and you go "Whaaa?", and nobody is expecting you to know the whole long history so you kind of have to throw completism and continuity out the window a bit.
If you can do that, you'll be fine. I came in with Bendis, and I didn't have a problem picking everything up.
