If you want to get the whole saving/investing thing started early, I would just toss the money in a set of index funds. I recommend Vanguard (low fees and high quality product - index funds are more or less all the same), diversifying across a few different indices (depending on what you wish, you could spread it across the S&P500 fund, the international equity fund, a corporate bond fund, and treasuries).
AFTER THAT, I would then begin the "learning" phase. What most people do not understand is that putting your money in a few companies is unbelievably risky unless you really know what you're doing. You can't just invest in names you know, the key is how much you're paying for them. With your money tied relatively safely in index funds, I would start researching individual companies. Take a look at the Investor Relations section of their websites, and read through the most recent 10-K. Don't worry if its unbelievably confusing, it's honestly not meant to be fully understandable by the general public. Your first time through, look through the verbal parts. Read the sections that describe the business, read sections like the Management's Dicussion and Analysis - skim through some of the numbers if you wish. Watch, if you have access, financial news programs, the Wall Street Journal, finance sections of news websites like CNN. Go to Yahoo! Finance or similar sites and see what the recent news is for specific companies as well as the economy as a whole, and look at how this news is impacting stock prices. Use Investopedia and Wikipedia.
What's important that this stage is that you learn. Avoid getting trapped into the world of people who have never opened a 10-K but think they're stock market geniuses because their uncle's brother's friend's barber had a great stock tip. One really good thing to do once you get into college is go to the business school library if there is one and ask how you can get access to equity research reports of companies. I would recommend that, at all costs, avoid technical analysis. It's an interesting idea but at the retail level (what you and 99.9% of the rest of the public is at), it's just not a very good idea.
