I don't have a suitable system to hand to check, but my recollection is
that the GRUB installation peers under the RAID and looks at actual
partitions to find things to boot.  You thus set the boot flag when
creating the partition, not in the RAID dialogue.

You may hit problems with partitions that size.  Have you consider a small
(256M) /boot partition first, then a large LVM partition afterwards, to
hold everything else?
