1) Can't you try auto for the filesystem? May work.(also you could use diskdruid - I think that's the Red Hat version. In Mandrake, there is a disk-partitioning tool. It allows you to see the partition, graphically, and automatically slots in an fstab entry for you. Red Hat may well have something similar)
2) These digits indicate the order in which the disks are mounted and checked, I believe. So, 0 0 should be fine, I think.
