Welcome to Apple Support Communities
Snow Leopard is a paid upgrade, so you have to buy it at the Apple Online Store > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
Before buying it, open > About this Mac, and tell us what process the computer has got. If it's an Intel processor, you can upgrade. Insert the disc and follow on-screen steps to upgrade to Snow Leopard.
After upgrading, open > Software Update, and install Mac OS X 10.6.8. Then, if you want, you can install iTunes 11.0.4 with a new interface, or iTunes 10.7 > http://support.apple.com/kb/dl1576
