Your total available space would be 2 * 36 GB = 72 GB.

Can you select what?

Look above, no, you can't.

Please take a look at: 
http://www.gtweb.net/RAID_desc.html

.. or do a little search in google (or your favorite search engine) with the
following key words:
"RAID-5 description"

Hope that helps

Marc
