Are you using Sun Disk Suite, Veritas Volume manager or some other software? I tried to remain child-like, all I acheived was childish.

I've come across the same kind of issues, the way you do it will depend on the use of the system. We had a system with 12 disks that would be a database server. We basically configured it as follows.
2 disks used for the base OS and directories. The disk were large, 36 Gigs, so we simple put everything onto the 1 disk i.e. root, export, swap etc... The second one was mirrored using disksuite.
The other 10 were used as followes (because we needed fast read/write for Database) We created 2 5 disk stripe disk sets with disksuite(Raid 1+0 or 10). Then we mirrored the first with the second and mounted it on the file system for the database. This was much better then using Raid 5 because of how slow it is with disk suite.

If I were you, I would also make sure I had at least 1 hot spare, and maybe even a 3rd root mirror that you could take offline once the system was in production. This would allow you go back to a stable root system if both mirrors were to get corrupted some how (i.e corrupted file mirrored to both disks) Hope this helps, of course depending on the application it's being used for, you may have other options.
