Should be okay,
Your md0 (/boot), needs to be made into a raid 1 array if its not already.

Grub should have no problem with your ext3 md device. If you set your bios
to look at your sdc and sdd device to boot first, grub should be found and
you can configure it to boot which OS you like. In theory. :)
Not familiar with LVM.
