This is my first crack at bcache and I configured a cache device with
defaults using make-bcache -C /dev/sda
Now I've got better info on my SSD and know what the block and bucket
sizes should be, however I can't run the command again with errors
that the device is busy.
I never did anythign beyond just creating the cache and backing
devices. I never registered the cache device, never created a
filesystem.

Yes, I had same issue many times. To resolve it you need to `echo 1 > /sys/fs/bcache/<UUID>/stop`, but maybe even `echo <UUID> > /sys/block/bcacheN/bcache/detach` before it.
