Here are a couple of organic links for you:
Crabtree Farms
Crabtree farms is a great little place just outside of downtown. Sequatchi Cove Farms is over the mountain in... Sequatchi Cove

For local organic shopping there is the Fresh Market or Greenlife (my personal favorite). We also have the Sunday events @ the Chattanooga Market. An outdoor'ish venue with lots of crafts, food and art.
We do have some cool areas to hang out. Little coffee shops and such. Sounds like North Chattanooga is RIGHT up your alley.
Speaking of wine! We have a grape stomp this weekend. Come on and join us
