Metadb replicas:
1. It's vital that you create metadb replicas on *both* slices. Otherwise the loss of a disk could destroy your database.
2. Having all the copies on one slice is no big problem, so long as you have them on multiple disks

Mirror:
1: That command means that you will have a mirror device called d10, it will write to d11 and d12 syncronisly - don't try to write to the underlying volumes
2: Yep, each mirror covers one slice - don't bother with slice 2 or your metadb slice though
3: Yes, this only ptoects you against disk failure, not deletions or filesystem corruption
