Ahem.... I'm a newbie with an HP 9100i Writer, and I want to burn Sonic Shuffle....

Well, to start off, I'm new at this "burning DC games" business. However, I have successfully downloaded and created the Utopia Boot Disc. I have all the files for Sonic Shuffle, but I need to know how to put it on a disc. I just don't know what to do with the .rar files and such . Will some, gracious, omniscient soul please help me??
