Wear layered clothing. When you get out of the home you should be feeling cold but not freezing; in 10 minutes of biking your body will warm and you might start sweating. Spend a few bucks on a comfortable backpack, or use a mountain bike with a rear rack to carry your stuff. Wear something in your neck for very cold weather. You can feel pretty dreadful afterwards if you expose it under cold weather. Wear sunglasses, not so much for the sunlight as for the fact that there's a lot of debris in the air, and getting random leaves of branches in your face can be a danger. Carry a spare for your tires. Bumps on the road can damage your tires quickly. Keep a towel and deodorant at work. Of course everything depends on how much you sweat, but it's something to take into account. If you'll be going through streets with lots of traffic, be sure to wash your face thoroughly after getting to work. I commute in the city and I get a thin layer of black smog over my face that needs to be cleaned to keep the skin healthy.
