First, put the swap also on RAID1, you don't want part of your memory to become unavailable is a drive dies. Using RAID has no use then. If a drive dies nothing will happen, your system will continue to keep running (if you put your swap on raid1 that is). But make sure you configure mdadm to send you a mail when that happens, so you know a drive is gone. For recovery, just replace the disk, repartition it and re-add the partitions to the raid arrays and your are done. The disks will resync and then everything is back to how it was.
