Good.

You did "mdadm -C /dev/md0 -v -e 0 -l 1 -n 2 /dev/sda1 /dev/sdb1"
Which is the usual way to set the /boot partition.
However, you did repartition md0, while still expecting to boot from md0.
That is "odd" to me. Just make a FS in md0 and use it as /boot (and root).

I could tell you what seems to be a reasonable setup IMO:
200Mb --> {sda1,sdb1} --> md1 --> RAID1 --> use as /boot
5Gb --> {sda2,sdb2} --> md2 --> RAID1 --> use as /
2GB --> independent sda3, sdb3 --> use as swap
Use the rest as needed. One option is:
rest --> {sda3,sdb3} --> md3 --> RAID1 --> LVM --> crete as many individual
disks as needed/wanted with lvcreate.
Having only two disks means to use only RAID1. RAID0 is too risky IMO as any
disk failure means a complete loss of data.

As I am not an expert in any sense of the word, I really can't tell you
where to post. I am a common user which is trying to help you. But, in this
list alone, there are three post from you with exactly the same content and
question. If you are not getting any feedback, perhaps you should re-think
of a different way to make your questions. And, please, allow more time for
an answer.
Thanks for your cooperation.
