At what temperatures should wine be served?

The type of wine you are serving will greatly influence the temperature at which you should serve it.  At the most basic level, as you probably already know, you should serve white wines chilled, and red wines at room temperature.  The temperature at which you serve your wine will greatly influence its taste.  It is for this reason that cheap wines may on occasion be served at slightly cooler temperatures (to hide their sub-optimal tastes), while with more expensive wines great care is taken to let them achieve an optimal, almost warm temperature; thereby allowing them to breathe, and their aromas to be released.  Note also that cooler temperatures will reduce the bite of alcohol in wine.
