1) The raid is degraded and you need to rebuild it, probably like this:

Code:

# mdadm /dev/md0 -a /dev/sdb1

Don't reboot until the raid has recovered.

Be sure to consult the mdadm manpage ($ man mdadm) for more details.

2) You need to specify a valid root before issuing a grub setup command.

Code:

# grub
grub> root (hd0,0)
grub> setup (h0)
grub> quit

Be sure to use the correct root location.

See the Grub Manual section 3.2 Installing GRUB natively for more details.
