First you would no longer be referring to it as an array once each drive is seen as a separate logical drive. Most distros like kubunu, ubuntu, Zenwalk, and others are small where you can simply see a 10gb root and if needed for 2gb of memory installed a 4gb to 4 1/2gb swap based on 2 1/2 times the amount of physical memory installed.
Most distros that small however won't even need a swap and will simply run fine without one. Linux runs on far less memory as a rule then other OSs like Windows. As far as seeing both become OSed drives usually a dual boot with XP and Vista or one of those two with 2000 or another older version would end up seeing two drives while a distro will simply slide in on the back end of the drive seeing a small partition there.
Before you decide on going aheads and making any changes the most common advice is simply burning a few live cds and running a distro live to see if you want that one, another, or none at all. Not everyone is a Linux geek as the expression goes!
