The complete LHT comes with a triple and a juicy granny on the rear cassette.
The complete CC comes with a double and a less juicy granny on the rear.
Adding a 3rd chainring to the CC costs about $19 for the ring and whatever your LBS decides to charge you for labor to put it on. (my LBS did it for free). If the cassette doesn't get you a low enough gear, that can be changed out, too.
Nice thing about Surly bikes is that there is a large enough Surly cult that you wouldn't have any problem selling a Surly, if you decided after all that you really wanted the Trek or Specialized your local Trek/Specialized shop wants you to buy. (I'm responding to your question on your other thread.)
