Just as recommended per man 5 raidtab -> parity-algorithm left-symmetric,
chunk-size might need some experimentation, but I recall 32k is usually OK.

The software raid device will show up as /dev/md0 (or similar); use that
blockdevice for creating the filesystem on.

This is certainly a good idea. LVM will allow you to create many logical
volumes on a single software raid device; otherwise every block device you
want (ie, a separate filesystem) will require its own software raid device,
which will be a pain. Especially if you ever need to change sizes of the
devices or add/delete some, LVM will be a god-send.

Carefully, as always ;-)
I suggest you read the software RAID howto. I am surprised that RHAT doesn't
offer selecting software raid right in the installer?
Sincerely,
