I have not passed any of the tests, and am not licensed. If someone does this, they should have passed the appropriate tests - see:

I got hammered in a recession, and started reading CNN/Money -
http://money.cnn.com daily to try to get an idea when the economy will get better.
I would say this, though: buying individual stocks will require too much time to research and pick the right time to buy and sell. You are likely to be better off if you buy a fund that is tied to an index - like the S&P 500 or Russell 2000 (small cap). You will be investing in more stocks and diversifying your risk. International funds are a good option too, but may have more risk.
If you get an account with ETrade or Schwab, they should have online tools to help you pick funds, but you need to look at the 'load' and fees. It takes $1,000 to open a Schwab account and $500 for ETrade. I do not know about TDAmeritrade. These are pretty easy to use, and you should be able to link them to an external checking account, so you can transfer money back and forth - and get a debit card on the checking account attached to the brokerage account.
It is probably worth splitting your investment into 3 or more funds with the percentage based on the level of risk you are willing to take with each amount.
If you do buy mutual funds, there may be a redemption fee if you sell within 1 month or some other time period. This will be described in the web page for the fund, and isn't buried in fine print.
