Regarding kashrus, as I am unable to obtain kosher meat in my city, there is certainly no need to keep separate kitchens.
I think the appropriate thing to do would be to abstain from meat if you cannot find anything kosher.
I think it'd be equivalent to buying pork tenderloin because they were all out of chicken when you went to the store, and you had to get something.
*GRIN* Kosher ham, huh? How entertaining! A lot of Jews do exactly what you are suggesting. My Rabbi I think does that. At this point, I am on the ladder of observance where I consume appropriate animals, and find kosher ones as often as I can. It is an interesting thing. Even when I was totally non-observant, I always found pork repulsive, except for pepperoni which I loved. I do miss that stuff. The rest of it I never had to miss, because I always thought it nasty.
My wife's family is big on pork, but they have learned to buy me something else for cookouts, and they at the very least keep it separate from the pork. Granted, the grill has been used for pork before, so its by NO means strictly kosher, but they do at least clean it, and keep the juices from mixing as much as possible. Well, one does what one can. Of course, Tom will call me a hypocrite. And I shall say that he should be killed.
