I have an interest in this.  Would it be correct to assume that, while we'll only be playing as Dunmer, we could interact with sympathetic non-Dunmer NPCs, like the Kahjiit traders and the Argonian Dockworkers, or even one-or-two non-asshole Nords and (later on) contacts from the Imperial Legion?

You assume correctly (although Imperial legionaires would be pretty rare in Windhelm). Having one or a few sympathetic Nord (or other) acquaintances could increase the drama even more when the story reaches its climax.
