4alpacas, if you're not already a GardenWeb member, I'd recommend checking it out. There's a forum for pretty much everything imaginable; the vegetable garden one is pretty active and has loads of info in the archive. My favorite veggie gardening book is the Vegetable Gardener's Bible - can't think of the author's name off the top of my head, but it's a good beginning book. In zone 9, you could be growing things like broccoli, cabbage, fava beans and spinach over the winter, and probably starting summer crops in like, January. Lots of opportunity to feed yourself year round, but there's also potential for burnout, so keep it low maintenance to start out.
I just have to say HOLY CRAP when it comes to spaghetti squash. I am going to be giving the stuff away to anyone who will take it. Even with my dog lifting some immature fruits off the plant, I am going to have like, 25-30 squash by the time this thing is done, and some of them are way bigger than the ones from the grocery store. This is just a single plant, or maybe two seedlings from the same pot, and it has gone rampant.
My new garden area on the south side of the house is proving to be fantastic for okra, eggplant and sweet potatoes. The area is a total heat sink, and they have been cranking. Mission of having enough okra to freeze for winter gumbo accomplished and then some. It's proved to be a bit too hot for one of my two hop varieties though, so I'll need to dig those up and rehome them to a less brutal environment after harvest is over. Also getting unbelievable yields for the little 4' row of pole green beans, as in, gallon bags of them. I think they're Emerite variety, and though they took a bit to get going, they are insanely productive now.
Tomatoes are all over the counter, and I've got orange and red bell peppers coming in finally, too.
