I've giving it a try, but have some questions.
The buttons have been given each it's own I/O pins. But you say
I have a resistor that has 10ohm, is that enough? And correctly placed?
The LCD display I have connected excatly as shown in the tutorial at Arduino, I think.

Now, you also say
With that you mean that those need to be connected to the ground wire?
