I am hoping to link my new, custom templates [which are located in a specific Revit 2013 Title Blocks folder on my server] to the Title Blocks folder on Revit 2013. The goal is to only have these title blocks as an option instead of the standard Revit title blocks.
We would like to be able to make changes to these Title blocks in Revit 2013 so it will be directly connected to the TB folder on my server.
If I understand what you are saying, you can either load the title blocks from your title block folder into your Revit template file -or- with your template file open, edit the title block families and save them to the title block folder. I believe either action will "link" the families in the template file to the families in your title block folder.
Note that editing the title block families outside of the template will not automagically update them in the template file. You would still have to reload the families into the template file(s) to update them.
