What temperatures should I keep my refrigerator and freezer set at?

For a refrigerator, if it's cooler, items like milk and meat last a bit longer. However if I set it close to freezing then some items start showing frost on them. What temperature should I set my refrigerator to for best overall results?
Since the person answering is likely to know, I'm also asking what temperature I should set my freezer to.

Thanks for posting and using both celsius and farhenheit temperatures. In America we don't not use or understand common Celsius degrees.
