Moving to Abu Dhabi - Need some advice.

I have been accepted a position with ADGAS starting next month. I have never been to Abu Dhabi before and am concrned about a few things. I was told the housing they provide is fully furnished. Does anyone know exactly what that means? Also, Grocery shopping will be important when I first get there as food is kind of important. I don't know if they will help me with that, or if a taxi would be the best bet.
