Well, you should try to have a pretty balanced workout. I'm not sure if you biceps are specifically small in proportion to the rest of you, but I'm going to venture that they are. Try out this link for some good starter weight training info. And here are some great bicep exercises.

Try eating. You are underweight.

An inch on your arms for every 15lbs of weight gained. How much of that inch is muscle and fat depends on your workout.
