The best I can help you is as below, this will also avoid you being tricked by the taxi drivers at the airport.

Once checked out of immigration, go to lowest floor of the airport, take the KLIA express, this will cost you RM35.00. It will take you to KL Sentral. At KL Sentral, buy coupon for cab/taxi at a counter meant for cab/taxi, it's near a main entrance, ask the information counter. Tell them your address and they will tell you the price of travel. If you agree (this is a safe and fair deal), they will provide you the coupon and direct you to the cab/taxi waiting stand which is the main entrance. You might have to tell the driver the address again. Oh! You pay the drivers with the coupon and not cash. Remember this!

I am directing you like this because, it's safe since you are new here and you won't get lost. There are other mode of travel which will cause some hassle and might get you lost if you are not familiar.

The better way to go if you not familiar with that place, is using the Airport Cab!
