I've never taken a PDC but it seems to me like all of this information is readily available on the internet or from books. I may be wrong but I'd spend my money on seeds or plants instead.

I think the Sobkowiak strategy is very solid. That's what I'm going with as well.

As many as possible. Keep planting and keep collecting cultivars or planting seedlings. If you've got the space just keep planting trees.

I'd recommend contacting Cliff England (also in KY) and get some material for a few jujubes, pawpaw, Asian pear, or hybrid persimmons. He's a wealth of information and could really help you in cultivar selection.
