New to Blogging

So, today is the first day of my blogging experience. I have been cruising several garden blogs throughout the US and UK. We are getting ready to landscape our backyard and include a veggie garden spot. I ordered the All New Square Foot Gardening Book and am looking forward to trying to figure out what to do. I have always dabbled in gardening...currently we have 2 tomato vines and herbs. But, we have not done anything of this size before. Our home is in Central CA and the yard is quite large. We are considering 8, 4 X 4 gardening areas, enclosed by some sort of decorative fence. I think along the back there should be some sort of trellis for beans or gords. Attached is a picture taken last month in the garden at Monticello, VA. Anyone out there who has ideas of what we should start with, please we are young gardeners!
