As far as tread goes, those should be preferable to your knobbies on pavement. They should fit as well.

I can't find any information of them regarding puncture resistance, so I assume they don't have anything worth mentioning (your current tires probably don't either). Many more expensive tires have substantial puncture resistance, making them much more reliable for commuting. You can get around that by buying and installing Mr. Tuffy tire liners, but they add about $20-$30, which is getting into "might as well buy good tires in the first place" territory.

Those should work, and will be an improvement, but I recommend seriously considering spending the extra money up front and getting good tires with built-in puncture protection. Continental, Schwalbe, Vittoria, and even Kenda all have 26" road tires with puncture protection at various prices.
