Instead of looking at stocks, look at ETFs and mutual funds.
If you want to paper trade, get a Yahoo! account and set up a portfolio in their Finance section. Give the portfolio $50k in starting cash and buy five stocks, each getting as close to $10k in each stock as you can. Then let it sit and watch what happens. It's cheaper to paper trade first, and less risky.
AND dd1101 is giving some good links. We used the StockCharts,FINVIZ and Investopedia in my stock market class a couple semesters ago. The book we used was A Beginner's Guide to Short Term Trading by Toni Turner. We didn't really use it though, seeing as the professor operates a business and knows his stuff. And read as much as you can, watch CNBC, Bloomburg, Fox Business, whatever you have. Just soak in as much as you can for a while until you feel confident in actually moving money
