The large amount of "Other" indicates data that iTunes can't recognize. A Restore will fix that. You can restore from your backup and retain all of your app data. I have done this to resolve excessive "Other" and no data was lost.
This article will explain the restore process and show you the screens you will see during the restore: http://support.apple.com/kb/HT1414
If the problem still persists after your restore, you may have to restore again and set up your phone as a new phone. In this case, you will lose your app data, but your phone will work properly.
