For the third question I think that a check of library or the WFH can help you too(see the xxxx but for the library depend of your installation):
Code:

//STEP010U EXEC PGM=DSNTIAUL
//STEPLIB DD DSN=DB2.DSNEXIT.xxxx,DISP=SHR         
//         DD DSN=DB2.DSNLOAD.xxxx,DISP=SHR         
//         DD DSN=DB2.RUNLIB.xxxx,DISP=SHR         
....
//WFHxxxx  DD DUMMY
