No. The mbr is most likely still in the first sector, but if your not
trying to make a bootable copy, then you don't need it.

I hope you're not planning on installing on the same drive that's
already failed?

It depends on whether the filesystem is intact. If you're lucky, you'll
be able to simply mount the rescue image and copy files. If not, you'll
need to rebuild the files with a recovery tool. ddrescue only does the copy.

Not usually, but it depends on what's wrong with your drive.
