I've heard of all those guys. I have started to be unable to stand most "serious" cartoons and animes, but Evangelion still has a lot going for it. It has very original creatures and characters considering that underneath all the psychology and stuff it is basically just another "mecha" show.
Jhonen Vasquez has definitely inspired my art, but his comics are sort of creepy. Which is the point I guess. Roman Dirges art is not as good as Vasquez but his comics are definitely more light hearted dark humor.
Btw, did you check out Cam De Leon's work? It seems like something you would like.
Here is another site for an artist I don't know much about
