Siting, quantities etc of fruit & nut trees, grapes, berries, livestock etc for a family for instance.

Agricultural Extention service could help you with your soil, trees, fruits. Personally I wouldn't rely on them for animal care.

General forums such as this one are a good source for real=world solutions. There is another section dedicated to types of plants, very knowlegeable folks on those forums.

There are several books out about farming on small acreage, I can't recall the names but a google search should bring some up.

I'd start with chickens, & work my way up.
As far as barns go, if you have hills, position your barn at the top of the hill-less hoof issues & much drier. Make you new farm life easy-use a pole barn or free-choice enclosed walk-in barn for general lounging & feeding of livestock, then an area inside your main barn for hay & equipment storage & several stalls "in case"(kidding, sick animal, lock down for any reason). Livestock are not fragile unless they are treated that way-just remember change management methods slowly easing into the various seasons/forages.

Cross-fence your acreage, plan on electric fencing eventually. Decide which livestock you would like, read about their care & disease issues, then purchase from a local knowledgable breeder NOT the auction house.
Join a yahoo group for each species you would like to own/raise & start asking questions. Know what predators are in your area & build your facilities for defense-maybe even a livestock guardian dog would be in order.

Take one project at a time, or you might be overwhelmed. Keep in mind some things take longer, like raising a goat to breeding age or waiting for 3 foot high fruit tree to bear fruit. Plan accordingly.

Food bill went from $140/2 week to less that $20 a month. It takes work to do this, but when you love what you’re doing is it really work????

The blade of the hoe is just a thin strap of metal that is sharpened on both sides. You do not cut into the soil; just drag it on top cutting the weeds off at the surface. Eventually the surface has no more seeds shallow enough to sprout. It is not necessary to till between the rows where you walk.

The soil in the rows will stay loose if properly mulched. I mulch with Canadian Peat Moss (CPM) or compost. Around the corn I use CPM mixed 75/25 with fresh chicken poo. I use CPM because it will loosen clay, hold moisture, safe to put tightly around plants, has very few weed seeds and hold the soil temperature at a constant level especially on cool nights or hot days.

A good strap hoe cost $30 to $40 and will last 50+ years. I just bought the one I have now because the old one finally could not be sharpened any more. Grandma bought it in 1956 when I was 5. It had seen many growing seasons.

Now Brendasue, don't be goin' 'round a tellin' everybody miz secret.
