Anytime, doesn't matter. Create identical partitions on both disks (I
set 500 MB swap first, 200 MB / next, the rest /usr where /tmp
-> /usr/TMP, /var -> /usr/VAR, /home -> /usr/HOME, reasons behind it,
doesn't matter). 

If they differ in size, check you have same disk geometry, if not, force
it with fdisk (make second like first). Rare problem, I hit it of
course, you might be more lucky.

Set partition types to FD : Linux raid autodetect (cfdisk is your
friend).

Traditionally, I has been recommended against putting your swap space on
SW RAID, so don't do it. Set up two swapspaces instead ('mkswap',
'swapon' and editing '/etc/fstab' are helpful).

Create SW RAIDs:
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/hda2 /dev/hdc2

That is if you actually put swaps first on /dev/hda1 and /dev/hdc1,
respectively.
