Basic Settings 

Let's start with enabling "Development Mode" in user settings.

If you are an administrator just go to Setup -> Personal Setup -> My Personal Information -> Personal Information and select:
- Send Apex Warning Emails
- Development Mode
- Show View State in Development Mode (optional, it enable the View State tab on the
development footer which shows the performance of your Visualforce page)

 First option will include you in distribution list when apex error occur, second will enable development in browser which is far more convenient than development using Eclipse only. You will be able to see results immediately.
