Thanks for your advice. I found a flare wrench at Auto Zone even after the manager didn't know what it was and said none were in stock. The dern thing worked and didn't tear up the brake fitting.
Now the bearing; it is pressed on tight. I can see it would be awkward to remove & replace with my few tools and abilities. However, I'll get it figured out. The right side was devoid of grease or lube of any kind and the bearing looks like it got "baked" pretty good. The brake backing plate really makes it difficult to get to. Ought to be a challenge that should be overcome without too much trouble (cross my fingers).
