Will I lose all my data (documents, pics, music, etc.) if I download OS X Mountain Lion? or does it back it up automatically or do I have to do it manually?

Although it's always a good idea to have a reliable backup before doing a major system upgrade, Mountain Lion does not touch your data or third-party applications. It only replaces system files.
