Don't take financial advices on the internet! You have a brain and you're allowed to use it, so think for yourself.
500$ is not really much, you will pay a few % fees (depends on the broker, I pay at least 35$ for one trade).
What could help you with "getting started" is a virtual stock trading game. There are several on marketwatch.

I have a similar problem.
What I can provide is a workaround.
(Note: Menu items etc. may be named a bit different from what I call them because I have a German console and don´t see the English menu)
1. Go to: Setting - Power Settings
2. Select the energy saving mode instead of fast boot mode
3. Power-off the xbox
4. Start the xbox (via tha button on the console or the controller since kinect will not turn your xbox on in power saving mode)
For me that solved it but I am not satisfied with that solution since i cannot wake my xbox via kinect now and xbox does not power on my TV on startup now.
I hope this issue will be addressed soon so we can make use of kinect as it´s supposed to be.
