I'm no expert, but a couple of books that people all over the net keep recommending (and I join them with my little $.02) are:
The World is Flat - Thomas Friedman
It's a much more in depth and nerdy version of 4 hour work week. Which, fwiw, is basically a crap burrito. A thin wrapper of marketing surrounding a thick, chewy center of indigestion causing glop. It's VERY much like most of the ebooks out there today: useless but emotionally engaging. It's the diet coke of advice, just one good idea: outsourcing. Which Friedman covers in a LOT more detail. If you buy it, get it from Barnes and Noble 'cuz they'll let you return it if you don't like it.
The Science of Getting Rich - Wallace Wattles
You can download in .pdf format for free:

It's sort of "Think and Grow Rich, Motherf%^ker!"
It's a really shortened, "Shut up and start visualizing" tour de force. I recommend reading both. Think and Grow Rich is available online for free also, but atm I can't remember where from. If you can't find it PM me and I'll try to dig up a link.
Not strictly SEO/blackhat related, but it'll teach you a lot about how to think about the learning curve.
Thinking is the hardest work there is, which is probably the reason why so few engage in it.
