I've never lived there, but would love to! What can't you grow there in zone 8!?
Tedlin recently posted this really nice link about what people in different regions of the country find grows best for them:
It shows these as the top ten crops for that region:
Bush snap bean
Pole snap bean
If you are moving now it will be too late for broccoli. But you can buy tomato and pepper plants, and probably still plant beans and squash from seed. For the fifth one, I would do swiss chard, just because I think its the easiest most productive thing you can grow in almost any garden.
