Three of the four faults listed in your scan are listed in the Ross-Tech Wiki (http://wiki.ross-tech.com/index.php/Category:Fault_Codes) Search the Wiki for information as to possible causes.

The O2 sensor fault could be the source of fuel trim problems. The fact that it is intermittent may just be a loose connection.
