That collection of codes could theoretically mean failed O2 snesors and failed alternator. However, since they have occurred following a plug and wire change, the more likely cause is loose connecotrs and/or grounds. Recheck all the connections you may have deliberately or accidentially disturbed while changing the plus and wires including any grounds in the vicinity (eg. on the side or back of the cylinder heads) . Finally, those codes can occur from water intrusion into the affected connectors if you cleaned the motor during all this.
