I'll agree with all the previous posters and suggest an additional resource that I found extremely helpful:
http://personalfinance.byu.edu/
Whether you love or hate BYU is irrelevant. The site is chock full of easy-to-understand information about money management, and it walks you through from the very beginning basic lessons on through more complicated investing, etc. etc. The good thing is that you can go at your own pace and take what you like and leave what you don't. It's easy to understand and very helpful.
