FN,
Carl's dead right. However, I would like to add by recommending a few good books - always a good investment and to which you will constantly refer for years:
Natenberg, Option Volatility and Pricing. This is for the basics and strategies.
Hull, Options, Futures and other Derivatives (6th edition). For the theoretical. Pretty advanced but written with clarity. If you don't understand it, you learn to understand it. I've just bought it to replace my 2nd edition.
You could also consider Hull's Fundamentals of Futures and Options Markets, and his Students Solutions Manual (accompanies Options, Futures and other Derivatives).
