The only place I could find online was the Blue Ridge Permaculture Network [http://www.blueridgepermaculture.net/resources.html].

Another avenue might be your local Cooperative Extension Service. If the word 'permaculture' throws them, immediately go back to basics and give them the bare bones of what you want: one acre of steep hillside that you want to plant in weed-resisting (possibly native) plants, preferably at least some that produce food.

Other useful info would be degree of slope, type and pH of soil, orientation to sun, temp. min/max, exposure to wind, etc.

The first thing that comes to my mind is berries like blueberries, lingonberries, mulberries (trees, I don't know how large they get), etc. Googling 'small fruits' may produce more info. But the Co-op Ext. should know what will grow there.

Books:
The backyard berry book: a hands-on guide to growing berries, brambles, and vine fruit in the home garden by Stella Otto

Uncommon Fruits for Every Garden by Lee Reich

You might also investigate cover crops, as both a weed control (perennial or self-seeding) and as a source of nutrition for the plants.

Have you looked into a garden coach? I've found that some of my clients who can't swing a full master plan still get some benefit from coaching. There may be someone in your area.

I would check with native plant societies in your area or talk to people about doing "restoration" on the slope. A steep slope isn't a great place to have a food garden, unless you terrace it. Plant natives that will help with erosion control. Start working on raised beds/terraces for the area right next to the house. That will be the easiest for you to take care of. The right garden coach would be a great help.
