My house is by the woods, too, as is the back view from my apartment. It sounds to me like you are over-thinking this. I don't think you need to do all that. I would kill the poison ivy, if you have any back there...maybe pull down some of the grapevines, if they are over-growing everything...but past that, I'd just leave it alone. Both my places (NY and the Heartland) are at around 41 degrees north latitude. I'm thinking your situation might be different if you're in a completely different climate. Any chance of you posting a picture?
I'm sitting here looking out my back door at a mowed lawn coming up against the woods...there are a few weedy, grassy places at the edge, some wild roses in bloom, and a barberry that probably doesn't belong there, but adds a nice red accent...looks fine to me...but maybe you are thinking of something more manicured?
