"McMillan on Options" by Lawrence G. McMillan is a pretty good primer.
I have also found the Options Industry Council site to have some pretty good stuff. There are tons of "Get Rich Quick" hucksters out there but this seems to be pretty good infor without a lot of hype.

As others have said, tread VERY carefully. I do some options trading, but it's fairly conservative and I have spent a lot of time educating myself.
