Interfacing with a temp sensor

Just got an Arduino Duemilanove and I'll be attaching a temperature sensor to it. I'm very much an amateur at this so I'm looking for a little advice as to how to get started. I need to be able to read and interpret the temperature sensor's data. (One Wire Digital Temperature Sensor - DS18B20 sku: SEN-00245 on sparkfun.com)

Background Info: I am fluent in C/C++ which is the interfacing language for this microcontroller and I am familiar with microcontrollers in general.

Up there on the right, there's a box with another box just next to it, labelled "search".
