Some of my favorite authors are David Dreman, Peter Lynch, Peter Bernstein, Burton Malkiel, Andrew Tobias, and Morningstar's own Pat Dorsey. Some of these are "stock guys", while others talk mostly about general investing topics. Also look for interviews that Warren Buffett and Charlie Munger have given. They don't write books, but you should be able to find plenty of commentary on the web from these two. You can read Buffett's annual letters to shareholders on the Berkshire Hathaway website.
There are dozens of ways to go about investing in stocks, and as many motivations. You need to find an approach that you believe in, so read as much as you can stomach. Then watch the markets, or invest with relatively small amounts for a while.
