Read Eisenhorn last. I was extremely depressed after I read it. Not because of the plot line, oh no, it was because I didn't want to read anything else because I knew it couldn't be as good!
Along with what experiment 626 and MSguardsmen have said, I would also recommend Ciphas Cain novels. They might not be super, but they're at least humorous. It about a commissar who's truly looking out only for his own hide, but ends up doing really heroic stuff and gets lots of fame.
