You can use the RAID/LVM article on the wiki :

http://wiki.archlinux.org/index.php/Installing_with_Software_RAID_or_LVM#Partition_the_Hard_Drives

I used it in the past to setup a few systems with RAID and with or
without LVM. So its your call if you want to use LVM or not.

Also note that the article uses 3 swap partitions in a RAID 1 (total
2GB swap). So you will have to ajust the instructions for your
situation.

Anyway, it will give you a good idea what the commands look like.
