Alright.. got it sorted out... Here's what I've learned..(please anyone correct me if I'm wrong):
Contrary to what I thought, using the Highpoint driver is really still just 'software raid' since all of the computational work for the RAID is done by the driver using the computer's resources. That being said, if you're stuck using software RAID, you may as well use the linux native software RAID since it's more mature, stable, and flexible that Highpoint's drivers allow for. (For example, you can do RAID5 with Linux software RAID, but not with Highpoint's drivers.)
Once I figured out what I needed to do, this page walked me through everything I needed to set up the array:

Hope this helps someone else...
