Liza, I was also just thinking that I don't know where you can get seedlings in the fall as most nurseries only stock on the spring. Even for spring planting some veggies are so really really easy from seed that it is so better alternative to costly plants. Beans, peas, cucumbers, squash, any type of melon and most greens like your spinach and Bok Choi are very, very easy from seed.
Are you planning on bush beans or pole beans? Bush beans stay short (about 2 feet or so) but pole beans climb and need some sort of support. In fact peas need something to grab onto also.
You might want to put up a trellis at the back of the garden for those climbing vegetables. Or up near your fence that I see in the background.
