How exciting
Gardening you should be able to feed yourselves really well plus canning. You will need basic tools, and see if you can barter something to get someone to rototill the garden for you. As for books, the very best book to get you started is Carla Emry's Encyclopedia of Country Living. Info in there on gardening any crop, livestock, butchering, orchards, just tons of fantastic info!
Best of luck with your new lifestyle!!
