Hi, the same applied for me, wehen I tried to get used to mysql!
So firstly I recommend that you download the Mysql dokumentation and read the chapter about Grant tables (may sound unlike!)
Then you should have at least a basic knowledge about how to insert data into a table.
With this combination it should be possible for you to insert the data even through telnet.
By the way: when you've installed phpmyadmin, you could enter the relevant data with this tool unless you haven't the rights.
Hope I helped you
