At the outset let me caution you that you have to understand the fundamentals of investing, appreciate that one has to be prudent in investing. You must also be aware of the trade of between risk & reward with various types of investments and the importance of allocation of your portfolio between different classes of assets, based on your financial goals, risk appetite, savings potential and age profile.
Even before going in for investing I suggest you clearly write down your financial goals. Let this set the broad parameters for how much and in what financial instruments or assets you invest.
You can try to get useful inputs from the following sites

Investment is a proactive business and you must periodically evaluate your performance.You must therefore also create a portfolio in Stock/Share Market Investing - Live BSE/NSE, India Stock Market Recommendations and Tips, Live Stock Markets, Sensex/Nifty, Commodity Market, Investment Portfolio, Financial News, Mutual Funds or some similar portal and evaluate your performance over a period of time.
Finally do remember that greed and fear are the 2 most compelling reasons that drive the stock markets in particular. Don't be a victim of these.
