The Smoke is a great choice, and a great bike for a person of your size. I started above that weight on an old Raleigh MTB that held up under me for a lot of miles, then a Specialized MTB that also held the weight. Keep an eye on your wheels, but my guess is that you'll have no problems with it.
Now, about the bike itself, the stock tires on the Smoke 2-9 are great! I have 700x37 Contacts on my Surly, and I absolutely love them. They roll very well, and provide a pretty nice ride along with good puncture protection. I was going to replace them when I got the bike, but since have grown very fond of them over the 800+ miles I've ridden on them. I've ridden pavement, gravel, crushed limestone, dirt and even some wet gravel/mud. Run them at 80 psi and you'll be just fine.
When it comes time to replace them (which may be a long time, mine are above 800 miles and have very little wear) you might consider Schwalbe Marathons. Great tires, well regarded by many. I'm going to pick up a set of Marathon Cross tires for the winter as I know several folks who have them and can't say enough good about them. You'll be hard pressed to find someone who does NOT like their Schwalbes.
That being said, the Continentals are great, and have served me well. For pavement I'll likely just keep replacing them with the same - great, great tires.
