Look to VMware Converter to either P2V your running boxes or to import your Shadow Protect images. I have seen some recent activity where the newest 4.0 versions of shadow protect are not supported, but version 3.x are.
So far as your raid arrays - you can pretty much decide when you create the VM where it will go. For a smaller environment like yours SATA raid is probably adequate for OS disks, and I would use the faster datastore for DATA disks, like for SQL and your Fileserver.
You indicated RAID 1 - which is great for performance, but offers no redundancy. I would consider instead RAID5 that gives a good tradeoff for performance and redundance, or RAID 10 if performance is the key consideration.
Good Luck
