VRS Front Grill (Chrome) & Gearbox Issues

I got caught out and ended up driving in a sandstorm in Qatar, the front chrome grill is shot. Any advice on how much the grill costs to replace (both parts) and a suitable place to purchase.The extent of the bodywork has not been assessed but I'm sure it will need detailing at the very least, and to add good measure the car popped a headlight bulb and the engine light came on..........The car is in the garage, apparently its a gearbox fault after 1700km :( Any help much appreciated.
