Hi Garth,
You said "but again I am unfamiliar with how to schedule a DTS pkg from the agent"
When you have the package open in SSDT under Project on the ribbon, select Deploy and select the SQL Server. This will save the package in SSISDB. Create a new job in SSMS on the SQL Server you deployed the package to and create a new job step, name it and select SQL Server Integration Services Package on the type drop down, Enter the Server, navigate to the path and select the package you deployed. Add a schedule and viola, you have it scheduled.
