'Now Playing' oled display for Media Player (xbmc)

I am completely new to Arduino and the programming language, so forgive me for my ignorance. I am building my own Media PC based on XBMC, but I am disappointed by the quality of case displays out there.

I like to use an large oled screen (256x64px) and think the arduino platform could be ideal for this. I looked around for days now to see if there are project like this, but have not found one yet.

The arduino has to recieve JSON-RPC (XBMC interaction language) and display it on e oled display.

I honestly don't know where to start... I probably have to write a translation script?

Any help or direction is welcome.
