A great start is to read the several tomes that are almost universally recommended by long term survivors of option trading.
From novice to advanced;
Options by Guy Bower
Options as a Strategic Investment by Larry McMillan
Options Volatility and Pricing by Sheldon Natenburg
These are all available from Joe's bookshop
In addition, I like
Trading Options to Win by SA Johnston (available from Joe)
Options: The Hidden Reality by Charles Cottle (available from
www.riskdoctor.com)
