Tamiya make a left hand and right hand cockpit, but they are pretty universal so pick which side of the road you drive on and get that one.
That is correct. There is also a driver/navigator rally cockpit, but they do not sell it separately.
You can go pretty creative with the cockpits. Even though you can just paint most of it black, they didn't skimp on details.
EDIT: Oh yes, and this will help if you plan on going box art with the decals:
