I've been thinking more about this. Are you an experienced gardener? This is a fantastic idea, but planting a huge productive garden from scratch in one year sounds overwhelming. Have you read about permaculture? It's when you use food plants as landscaping. The 'Food not Lawns' movement is pretty awesome too. Get familiar with the concept of microclimate.
Take your time getting to know your lot. What areas get sunlight during what parts of the day and for how long? What kind of soil do you have? If you are going to put in trees, plant them the first year and think about where they will cast shade. What is the purpose of this garden? Are you just supplying your own kitchen, or do you want maximum production to sell at a farmer's market? Will you need expensive equipment like a rototiller? How will you deal with pests?
I would start with the plants that you have already cultivated, then add only a few more species each year. Don't plant things that you don't like, 'just because'. For instance, if you hate oregano, don't plant it just because every herb garden has oregano. Visit greenhouses and find plants that really appeal to you. Look at them, touch them, smell them, taste a leaf. Another thing to be aware of is that herbs planted too close together can exchange flavors.
The whole garden is a living organism. Build it up slowly. It will change every season and from year to year.
