My recommendation for a ND (also a midwife) is Katherine Zeiman. Google her. She works in Gresham. She delivered my son and she's really a neat lady and knows her stuff pretty well, too.
Be sure to check out the People's Food Coop (google it for location). It's got pretty decent prices on organic foods, and you can get a membership that will get you discounts on a bunch of things that it sounds like you would be interested in. There is a Whole Foods, too, but the coop is better, I think. Smaller, but better. They even sell raw goat's milk!
Sorry I can't help you with the rest, but I'm sure you'll get lots of recommendations. And welcome to Portland.
