I posted a similar thread a while back, and got some good recommendations. You can take a look and see if any of them interest you.
Now, I don’t know which kind of comics you like. Your list seems to be mainly superhero stuff, although afaik 100 Bullets isn’t (It was on my list of comics to get, but I never got around to that one). Anyway, my absolute favourite comic is Dark Horse’s Conan, which is currently at TPB 13, plus a number of “extra” TPB’s which collect small one-shot stories. If you go for this I’d recommend starting with TPB 1 and not 0, which is about Conan’s childhood and coming of age, and is done in a different style. 0 is still good, but not very representative of the series. All of the TPB’s are selfcontained story arcs though, so it’s not too important where you start, although I like the (more or less) chronological presentation of Conan’s career.
Kull, also by Dark Horse, is good too, but is really just another Conan, only not quite as good, in my opinion, so you might want to skip that until you catch up to Conan and can’t wait for the next release. :D
I’d also recommend the Dunk and Egg comics, which are based on short stories by George R. R. Martin and set in his Song of Ice and Fire universe. Currently there are two, The Hedge Knight and The Sworn Sword. I like the art style very much, and the stories are great.
I also enjoy the Solomon Kane comics, also by Dark Horse. It’s basically about a bad ass puritan dude who travels around in 17th century Europe and kills demons and witches and such. Each TPB is a self-contained story, so you can just pick one to get you started, if you’re interested.
The League of Extraordinary Gentlemen is also quite good, and definitely worth checking out if you’re interested in the setting. Definitely better than the movie.
Finally, I’ve been reading and enjoying the Walking Dead. While I don’t like the tv show, I do like the comics, although they’re a little uneven in opinion. I kind of started losing interest around TPB 3 or 4, but then it picked up again. Then I kind of lost interest again around book 7, I think. I’m going to get back to it eventually, but not right now. The first 3 or so books are very good though, so if you want some zombie stuff, that’s where to look. They’re not self-contained stories btw, so you do need to start at the beginning.
Finally, I really like Serpieri’s Morbus Gravis. It has a very interesting plot, and I love the world, but be aware that it contains hardcore pornography. It’s not too jarring, in my opinion, but if that’s a deal breaker then this obviously isn’t for you.
Also, +1 for Sandman.
