This seems like a very easy choice to me. Obviously, go for the Nikon. Lenses are more important than bodies, generally speaking. The kit zoom isn't bad, but I think you're wasting your money on the body if that's the only glass you put on it; the D7000 and the K-5 have the same sensor, essentially, and very similar low-iso performance. Yes, the in-body stabilization is a god-send with Pentax, but you have less need of it with either of these cameras, and anyway, you'll be able to find fast, affordable lenses for the Nikon.
"the vast majority" of K-5's being "fine" notwithstanding (just how does one arrive at such an omniscient statement, I wonder) it seems a bad idea, whatever the make of the camera, to purchase one without convenient availability of warranty repair.
The K-5 is probably a better camera overall, but I just don't think you'd be able to take enough advantage of the minor performance differences with the D7000 to make it worth the greater risk, given the situation as you describe it.
The better weather sealing of the K-5 may decide it for you, I suppose (as long as the lens release button doesn't fall off; that's been known to happen!) but apart from that going with NIkon just seems more practical.
