The "lean" codes suggest a vacuum leak. Finding the leak can be tricky. Do a search on this forum for other peoples experiences and corrective action.

The secondary air code suggests a failure of the SAP system. The catalysts codes may also be related to SAP malfunction as you have two contradicting codes. The SAP helps to burn hydrocarbons on a cold start. Do a search on this topic. Open your hood and if your air pump does not come on for 60-90 seconds on a cold start up, it is toast and must be replaced.

Please report back your findings and corrective action.
