I can scrape up a few answers...
-Smallville's in the state of Kansas
-Pulitzers exist...or at least I've seen reference to them in other fics, so you're fine there.
-As for Kryptonite...I'm under the impression that as soon as Clark enters a room where it's present, he can feel it.
Welcome, welcome! I hope you have a good time around here!
