You are very welcome! Well, even though you haven't moved yet, congratulations on your new home!
I'm a bit confused though, are you asking the same question?
what can i do to prep for spring? i am planning on a rasied bed 4x4.
If so, do read the links I gave you. They should answer your question. If you already have soil in the raised bed then I would suggest that you either do the lasagna method or add at least 6" of compost and mix it in. Then plant a cover crop that you can turn under in the spring. If you don't have the raised bed yet I would suggest a mix of 60% SCREENED topsoil and 40% compost and then plant a cover crop. Mother Nature doesn't like blank spaces and if you don't cover the soil with plant material, she will.
If that doesn't answer your questions, please write back with specific questions.
Btw, DO NOT use treated lumber to edge the bed. You can just hill up the soil or use stone, blocks, untreated wood, etc. And, square foot gardening should work well in such a small space.
