While I had grown up around farms and farming [and even a cattle ranch out west] I had never done any of it myself. I decided to grow something simple -- Christmas trees -- and started planting, then mowing, then shearing, then spraying. My first lesson was that being a farmer means being a chemist and a mechanic. Stuff breaks and help can be a long way off. Then I was abruptly introduced to pesticides, herbicides, fungicides, fertilizers, and I don't know what-all.
Each crop or livestock will require its own set of skills and knowledge plus machinery so I would be cautious of diversifying too much at the start. And I would advise against such a large amount of land at the start. Try to get some time [internship] on a going concern to learn what they do and how they do it. I fear you are overreaching and will find yourself overwhelmed from the start.
