I did Done and Deploy, in fact deploy is grayed out if I don't hit Done first.
Only thing I've noticed now after poking around a bit, is in the dashboard/layout/edit dialog the fields are surrounded in ' ' marks whereas in the node dialog where they were entered they are not.
Anyway, its working now, actually it was working good enough for my purposes with the default icons, but I'm trying to learn a bit about the details of how this all works.
