Check out Professor Damodaran's website: http://pages.stern.nyu.edu/~adamodar/ . Tons of good stuff there to get you started. If you want more depth, he's written what is widely considered the bible on the subject of valuation: "Investment Valuation".
DCF is very well suited to stock analysis. One doesn't need to know, or forecast the future stock price to use it. In fact, it's the opposite. Business fundamentals are forecasted to estimate the sum total of future cash flows from the company, discounted back to the present. Divide that by shares outstanding, and you have the value of the stock.
The key is to remember that DCF calculations are very sensitive to inputs. Be conservative in your estimates of future revenue growth, earnings margins, and capital investment. I usually develop three forecasts: pessimistic, neutral, optimistic. This delivers a range of value instead of a false-precision single number.
This may seem odd: I find the DCF invaluable, but for the process, not so much the result. The input sensitivity requires careful work, and while a range of value is useful, the real benefit comes from being required to answer the questions to build the forecast. It provides a framework to analyze a business. You're just trying to properly fill in the boxes, estimate the unguessable. To do so, you pore through the financials. Skimming, reading with a purpose. In the end you come away with a fairly deep understanding of the business, how they make money, why they'll continue to make money, etc.
what do you mean exactly? Do you have a future target price and projected future dividend payments and you want the present value (time discounted price) of those?
The DCF formula is difficult to use for stocks because the future price is unknown. It is more applicable to fixed-income instruments like coupon bonds. You could use it but you need to predict / speculate a future price for the stock.

The P/E ratio and the Dividend yield are the two most important. The good P/E ratio for a mature company would be around 20. For smaller and growing companies, a higher P/E ratio is acceptable. The dividend yield is important because it tells you how much your shares grow even if the stock price stays unchanged for the year.
