Hello Merv!
Did you resolve the GRT problem? I got fullbackup working after following your steps with "REQUIRED_INTERFACE" key and whent through the documentation one more time.
I also got error on GRT backup saying that SHP server could not read backup images on master. So i added a "altnames" folder with a file named "No.Restrictions" after that it worked like a charm.
Go to : "install folder" "Veritas\NetBackup\db\" create folder called "altnames" if it does not exist. In this folder create a file called No.Restrictions.
I got the idea of no.restrictions file from this link:

Did you have another error on GRT?
