I think that is correct, yes.

I don't think you want to do this, that initramfs will not be the right
thing to boot the proper system -- it will launch the installer.
In fact, if you followed the rescue procedure then this is already what
is in your flash at this point.

Unless you have been deliberately cleaning them out then older kernels
should still be installed, but flash-kernel is just picking up the newer
3.12 version.
# dpkg --purge linux-image-3.12-blahblah
# flash-kernel
should do the job and flash the next newest version (need to run f-k by
hand due to #735093).
You could also download the latest kernel from sid, 3.12.8-1, which has
the booting bug fixed and manually install that.

Yes, that would be the first place I would look

snapshot.debian.org would be the second place I would look. See

I don't think you need to, the issue you are having is not with the
initramfs and in any case the installing/removing kernels should cause
it to be regenerated as necessary.
That said, there should be no harm in running that command.

I think it should all be there and should be working.
Good luck!
