In order to trade options, you really need to understand the greeks. Best to begin by just trying to get your head properly around whichever model is best suited to the market you want to trade, probably black-scholes. Sounds straightforward at first, but it is a tricky model to fully understand.
Unless you are only planning on being long options, and are happy without having a delta hedge, in which case, there's probably not too much to learn about them from a technical standpoint
All depends what you're planning on trading, and how you are planning on trading it... Let us know, and I'm sure you'll get a range of good advice, annd hopefully not too much bad advice.
*Good place to start if you want to understand the mechanics of options and pricing them is something like Hull, Futures options, and other derivatives. Or I'm sure there are billions of other books for a simpler explanation. If you want to trade volatility, or actively manage an options book, then look to things like Dynamic Hedging by Taleb, or The Volatility Surface: A practitioners guies, or Volatility: the secrets of skewness.
