I forgot to read my question before your answer... For the garden itself, I ended up going to the Natural Gardener in Austin and asking them about organic soil. They made a recommendation, said it was suitable for organic gardening, and I bough tit in bulk (VERY reasonably priced). I also drove to a small farming distributor and bought some Pro-Mix (the Micorise Pro type) for my herb garden. I've had great success!
We also installed worm buckets into each veggie bed. It's a five gallon bucket with worm holes that you bury in the center of your garden. You fill it with red worms and then just put your compostables into the bucket. The worms eat it and spread castings out in a six-foot radius, making the soil amazing. Just don't add anything citrus, any dairy, meat, or salt. Just veggies and unglossy paper products. You can find out more from Gordon at wyboswigglers.com - awesome!
