Sbagal,

Another link that might help you with on-the-spot Icelandic-to-English translation, before your trip:
http://www.translation-guide.com/fre...h&to=Icelandic

Also, if you run into translation problems while you are there, several shop, cafes, and even banks offer free internet service. You can go to a translator site and get the neccessary answers there. Not much help out on the ring road; but it helps that most Icelandic people are super friendly and speak English!
