this can't work, your telling grub the stage1 and stage2 are on hd1,0
and then removing hda which makes the drive that was hd1 into hd0, so
now grubs looking for them in the wrong place.

you need to create a grub boot disk, "cat stage1 stage2 > /dev/fd0"

then boot from this and do this or something similiar:
root (hd0,0)
setup(hd0)

do this with hda removed.

the only concern now is todo with your raid setup, and I know nothing
about booting raid with grub.
