You know a good way to get vege garden info is from your local nursery. I know it gets hot, hot, hot where you are so I'd say start those tomatoes now. On the whole I grow most of my tomatoes from starts, it's just easier than from seed and they are cheap in six packs. The weather here on the central coast of California has been unusually hot and I'm thinking I should be starting tomatoes and melons now myself. I agree with Weedwacker, there is no teacher like experience.
