As far as Deadpool goes, I recommend The Circle Chase and Sins of the Past. World War Hulk is also a really great arc to read, one of the best story arcs to come out recently with the late Civil War/Secret Invasion bullshit. If you're wanting to read some good graphic novels, go with the classic The Dark Knight Returns, The Long Halloween or if you've already read those Spider-Man:Reign is one of my favorites.
