The above relocate messages seems to be wrong.

Try to link your kernel at 0x400000, this may solve your problem. Also try to look inside arch/ppc/mbxboot/misc.c=>decompress_kernel() carefully, where you should relocate your compressed image at proper place.

Yes.

No, they way to solve the problem is to leave the Makefiles and all of the addresses alone, that is just as they are in the original sources. Simply build the zImage, load the image at address 0x200000 and jump to it.
