SQL Agent still attempting replication for deleted publication
It looks like you have some orphaned replication bits and/or orphaned replication agent jobs.

Note that Distribution.dbo.sp_MSremove_published_jobs will not remove your Distribution Agent jobs.  You will have to manually delete the orphaned job(s).

Locate the job(s) under SQL Server Agent -> Jobs.  The Distribution Agent job names will have the format Publisher-PublicationDatabase-Publication-Subscriber-integer.  Right-click the job -> Delete.

I hope this helps.
