If you have any modern OS (Windows XP+, OS X, or Linux) you will be able to extract the .zip file. It should open just like a folder and you will see the contents. Then, just connect your phone to your PC and drag those files over to their respective locations on your sdcard. You can make folders on the phone with ASTRO or the included Files app. Or, you can make them with your computer when you have the phone connected.
