I don't see why you'd attack the inns though. A Dwarf would most likely go to an inn and just make a deal with the barkeep, or say that the building was built by his ancestors (or relatives certainly) and demand some sort of beer payment.
Right, Mutual supportive fluff:
I: I'll probably mention the dead Greenskins, but I doubt any of my soldiers know the difference between a dwarven bolt and a human one, and my General would use this to boost morale by saying: Look what the Empire's done to these orcs!
II: Ooh, you want better units, Mister Reliable-War-Machines? Ok, maybe a bit harsh, but I doubt this would work, considering WE LIVE HERE! Most of the hunters, militia and some of the State Troops will have been brought up in this region, and will know all the shortcuts, and would be faster. However, it could be said:
"As we approached the <insert evil lair sounding name here> we met a group of Dwarven Rangers, they had arrived at the same time as our Huntsmen, and they communicated much helpful intelligence."
III: It may be a good idea that, if you have Heavy Cav from DoW, that they are Hunters of Sigmar, who fight Chaos. In fact, mention them coming to help you if your facing "evil" races. Why didn't a certain unit appear thoughout the game, they were fighting the Hunters, etc.
Personally, I'd like some kind of attack on the Wasteland mentioned, but I've been working on this with the Elves and the Brets in our negotiations.
Maybe even Marienburg?
