I'd suggest getting apt-get
for Fedora1. It can easily get past these dependency headaches. Download and install both the packages and run:
apt-get install k3b
If k3b can't be found you can just apt-get flac and then install the k3b rpm you downloaded.
As for the hard drive mirroring I'm not sure. You could easily copy your existing partitions to another hard drive with a simple script but I'm not sure how you could copy the MBR over as well.
