Philip, No need to worry about freeing this memory; the kernel does it automatically. The kernel will raise or lower the amount of memory used for cache depending upon the amount needed by running applications. Lots of memory used for cache is normally a good sign because it means you have plenty of memory available for the running applications and then some.
Cache significantly speeds up disk access times. You'll be very unhappy with system performance if cache ever gets to 0! :-) The memory item you should worry about is swap. If you are using large amounts of swap or your machine is constantly swapping you probably could use some more memory. Swap kills system performance.
