Do you know how to write a hardware interrupt handler? If not, you had better learn about that first.
After that you can try reading scan codes from port 60h from inside your handler, and read up on the PS/2 keyboard on the Wiki.
You get commands the same way you would if you were writing an app in C. By calling something equivalent to getch() (which you will have to write yourself), and by storing the characters you receive in a buffer.
However, before you can process commands, you will need some kind of command interpretor. That could either be your operating system's shell program, some way down the road, or a kernel debugger, rather sooner.
