Does anyone know how I might change a column heading from Campaign to Designation?

Oh okay.  That looks like a separate thread.  

Generally speaking when you "build" Change Set, which is essentially a glorified Zip folder that you put a bunch of "stuff" like new fields, changes to page layouts, code, etc, into, which will then be "Uploaded" into your Production Salesforce org, or an intermediary Sandbox, if you have a multi-step Development/Deployment Process. 

Anyway, if you're "building" the Change Set (adding components to it) that would be an "Outbound" Change Set.  

In the other org that you want to deploy the Change Set (changes) to, it would appear as an "Inbound" Change Set (after you've done the upload part)
