For books, I always stick with good old Natenberg. You can't go wrong with his stuff. It's as dry and boring as can be, but it will teach you the basics.

If you insist on paying for options info, then there are a number of sites out there that will be more than happy to take your money. However, I don't recommend any of them. I like my info agenda-free, thank you very much.
