What are some necessary tools, I will need to purchase?

I finished reading "How to make money in stocks" by William O'neil, and I subscribed to their Investor business daily newspaper. However in the book it talks about comparing previous annual earnings from the last 3 quarters and information regarding if the CEO himself invested in the company stocks. I would like to know what tools would I need to find this information. Or what do you guys prefer to use?
