[kubuntu] How to partition?

view story

http://ubuntuforums.org – Basically, I am trying to install Ubuntu on a previously Windows 7 laptop. I have a 320GB hard drive and will mostly only be using this computer for internet browsing and messing with the Linux OS. I am installing Kubuntu 12.04 through a flash drive and made it into an installer using "Universal USB Installer." I want to know what to set my partitions to, so that I can have one for the OS (Kubuntu) and one for everything else. Or others if they are needed, as I know nothing about partitioning a hard drive besides that it divides up the drive. So, what type and size should I give ea (Hardware)
