Ooh this sounds fun - you've got a long ways to go!
I'll skip the land acquisition stuff and mention a few things about start-up costs.
A farm start-up can actually be a fairly inexpensive business to start. A lot of the small scale farmers will tell you that it takes around $30-40k to start a diversified vegetable market farm. This is somewhat independent of scale as a lot of the major fixed costs do not fluctuate (much) with the size of the farm until you reach a certain point. For example, a $2,000 walk-in cooler may be enough to service a farm up to 5 acres (just an example). Personally, I don't think the $30-40k number is too unrealistic, especially if you want intend to do things right the first time and you're not planning on purchasing any big equipment (rent or borrow tractors if you can). I however, managed to start a 1 acre market garden for around $10k. This took considerable effort - tons of wheelin' and dealin', horse trading, salvaging, building projects into the middle of the night, coming up with homespun designs for implements, etc. If you are creative and savvy with craigslist you can save a ton of money. Of course the trade off is always the cost of time and effort.
For vegetable farming I can not recommend Elliot Coleman's ,"The New Organic Grower", highly enough. Fantastic book. A book by Richard Wiswall, "The Organic Farmer's Business Handbook" is also super useful. It focuses on financial considerations of farming and doesn't really touch on cultural practices.
