You can obtain a copy of your criminal records from the department of justice. This should indicate the needed information. Go to: http://www.ag.ca.gov/fingerprints/security.php and follow the instructions.
With regard to the case you were found not guilty you can also obtain documentation from the court file which should indicate the fact that you were acquitted. The court will certify the documentation if you need but there is a fee.
