An Admin will replace me next week. What Sys Admin / Repository / other actions do we need to take?

He is a member of the same App Admin groups as I am.  For the Sys Admin action that I recall--something about an administrator--Can he perform it, or do I need to?  I think I can reproduce my privileges in App Repository, so I'll try that now. 

Also, why can't he see 57 Scheduled Reports in the UI that I authored?  Their privilege is Manager.
