Any other gardening books? “Carrots Love Tomatoes” and “Square Foot Gardening” are some more suggestions, if you don’t already have ‘em.
Not 100 per cent sure about your intended terrain, but getting some kind of books on laying stone walls (particularly, laying them dry for boundaries and the like; or for that matter, laying them to build the house or components thereof) might be a good idea as well. :’)
Someone already cautioned about buying land from a friend. Real estate does bring out the worst in people (even worse than Demwit partisan politics in an election year). Get everything in writing after talking it over thoroughly.
Someone already suggested guns and ammo, also a good call.
Block and tackle or powered winch (for moving lots of things which will need to be moved, such as trees you cut down, rocks, etc). My dad used to pick up very handy old-style tools at the big used-to-be-Amish fleamarket in Shipshewana, but since you’re in Indiana, I’m sure you know about that.
Got the gun thing covered.
Shipshewana, I'd forgotten all about the big flea market there, Thanks
