Planning a first campaign

i will be starting a 2nd edition campaign in a couple of months, as far as I am aware none of the players have any experience with the warhammer fantasy setting, though they have played other rpgs.

I am looking to start things in a village the Empire somewhere between Altdorf and Middenheim. At least to begin with, I plan on sticking to events around that village. Problems with bandits and beastmen likely being the main problems.

But I have a few questions as I develope the plan further.

Is sticking to a relatively small area feasible long term as people start moving into more advanced classes?

How should non-human characters be introduced if anyone wants to play as one?

What other threats would a village in the empire face that would need adventurers to solve?

Thanks in advance for your help.
