No, you did it right. You don't need the partition table, just the actual 
partition.

Can you try: diskutil info /dev/disk0s3

Hopefully that will give you the real size of the disk.

Also try blockdev --getsize /dev/disk0s3

No. You are fine. Just find out the old size of the partition and create a 
new partition anywhere, just as long as it's the same size.

I wouldn't run ddrescue again for no reason - once a hard disk fails it 
starts getting worse the more you use it. You won't get as much data the 
second time, so keep what you go already.

Yes. To some other partition you are not using. Hopefully on a different 
physical disk, or it will be very slow.
