Garden–Help!

Remember last year, when I talked about putting the garden in the front yard?  Well, the time has come to start! We’ve ripped out most of the sod, leaving some grass in to act as a path.

And by “we,” I clearly mean Eric.

Here’s the thing–the way I approach most things is just to start them and figure it out as I go along.  I’m not much of the planning sort.  This has tended to be how I do just about everything–knitting, parenting, and this garden.  So far it’s worked out, but I’m realizing now I don’t really know much about how this will work! So I’m asking those of you out there who are much better gardeners than  me for some advice.  Here’s the front lawn as it is now, picture taken at 10:30 AM:

I definitely envision a squash/cucumber tepee in the center (#12), and some shade flowers or lettuce in #1 and #13, which will be pretty along the walk.  But what to do with the other sections?  Each one is about 3′ x 3′ in a wedge shape and the sun is coming from the south.  I know it doesn’t seem like a ton of sun, but we got decent veggies in our backyard last year and that patch only gets about 4 hours of direct sunlight daily and this is much more.  Some shade is cast by a large pine tree that we’ll be trimming, so I’m not worried about that. (I am worried, though about thieves,  animal and human.)

Thoughts? Suggestions? Am I crazy? Anyone else out there with a front lawn veggie garden and how did it go?
