@umbra21 - The best thing for pilling is to prevent it by getting fabric that won't pill. There are some kinds of really good wools that won't, and I believe some synthetic fabrics don't either. Generally they put something on the label if it's pill-free.
You can also stop it pilling by turning clothes inside out when washing them, and drying them on a line outside (or even inside) if you can, rather than putting them in a dryer.
If you've already got it pilling a little there are special pill-removers you can use, or you can try to carefully cut the pills off with a razor or scissors... but it's really easy to damage the fabric, so be careful if you choose to do this!
