Benny, enter as much information as you can possibly obtain. What you dont deem as being important now might not be the case in 12 months time, and depending how you do it, it shouldnt be any harder.

IMO you will need either Oracle or MySQL, either will do, and both very similar anyway. But, you will need to familiarise youself with SQL, and PHP if you want to make the job of manipulating/displaying the data much easier.

But if you dont know anything about programming you face an uphill battle, good luck.
