Pierogi, barszcz, bigos. Żurek is unusual and great, it's a sourdough soup. You can go to a milk bar (cheap subsidized eatery), it'll have an entire menu of the stuff people used to make at home. Schabowy, mielony, gołąbki. These aren't anything special but they're as local as it gets.

I wouldn't bother. They'll charge you a fortune and vodka is really nothing special. Most people wouldn't be able to tell the difference between a top shelf one and the usual in a blind test. It's an alcohol designed to go down smoothly with a chaser, not something to delight in. The more interesting are nalewki (colored vodkas), which are usually lighter in alcohol content and flavored. There's a massive commercially produced selection nowadays and some of these can be pretty good, if a tad sweet.
If you want a vodka tour that won't charge you out the ass, my advice is to go inside any given store and buy yourself a dozen małpki (lit. little monkeys, pic related). These are 100ml vodka bottles that go for ~8-10zł a pop. You can build yourself your own tasting experience that'll last you days for a fraction of the price.
As for other places, I'm not from Krakow so you might want to wait for someone with more knowledge of the region if you don't want the obvious (Auschwitz, Energylandia, which both would suck for NYE for wholly different reasons). The area between Kraków and Częstochowa is a lovely natural park packed with cool castle ruins, but I'm not sure how viable this is in December.
