Hope you get your array back, I'm not sure what else to try.
No backup?

Yes, you can create a seperate partition for /boot. It must be a single
partition, drive, or best of all, raid 1 array. Nothing else.
Without /boot seperate, your kernel can't load. 
/ can be a raid 5, or raid 0 or whatever.
Because your /boot isn't a fancy array, the kernel will load, tehn load
up mdadm to create your root raid array and then mount /.
