We go for organic eggs, but not organic milk--none of the local dairies are organic, though they are all rBST-free. The milk we usually get comes from a herd that is fed all-vegetarian feed, and they aren't given preventative antibiotics.
I generally try to buy organic when purchasing other foods, but that's not hard. It's also not hard to buy food that is produced locally--I live two blocks from the food co-op, and they have a special program wherein everything produced within a six-county block (with my county at the center) is labeled with a special Local Six label:

We pay a little more $ for local, organic food, but we save so much money by not eating meat at home that it more than compensates.
