1. "RE: Klingons and Rumors of Klingons"

Given the general lack of regard that all right-thinking people hold Voyager in, I don't think there are going to be all that many expectations to disappoint here. B'Elanna has a low bar to clear, is what I'm saying.
Really, I think you captured her essential B'Elannaness in terms of personality, which means that the actual plot-based details of her life are less vital. Making another original character would have been fine as well; that whole period was kind of a golden age in UF for the addition of characters who were spun from whole cloth rather than imported from elsewhere. (Ironically, many of them have ended up kind of falling by the wayside.) But I don't think this is the sort of thing that ought to haunt you.
Sidebar: I was pretty glad when Ezri showed up. I'm a goddamn giant DS9 fan; best Star Trek series by far. (Sorry, TNG. It is true.) But Ezri seems to catch an awful lot of flack from fans for, as near as I can tell, the grievous sin of not being Jadzia and not being played by Terry Farrel. So I like that she's kicking around in UF. And not bonding her with Dax, definitely the right call. That story has already told, it's called "Season 7 of DS9."
