Well a distribution is an easier way. All you do is write the image to a dvd and boot it up. Then, you install it and you're basically done.

So once you have a partition, you'll boot up the dvd, and then look for disk utilities in the menu bar. You'll probably want to format it as Mac OS Extended (Journaled)

Then you go on with the installation and hit customize then choose what works for your machine. It may take a few times, but it is worth it.
