Excluding changing springs or shim stacks, it's more about understanding what you're doing than actually doing it. Doing it might at most require the use of a screwdriver and spanner. If you just set the preload, you'll probably get 80% of the benefit for 20% of the work. It's probably under Sag or Preload adjustment in your manual.
You can probably just leave the compression and rebound damping at factory settings, but if you want to get a little more involved, set the compression dampening in the front to full soft, take it for a familiar run, then full hard. Same thing with the back. Then do the extremes of rebound damping front and rear, one at a time, and you'll start to get a feel for what those things mean. Once you get a basic understanding, put all the settings back to stock (except preload), and just start playing with it given your new found understanding.
I'd suggest this book if you want to really learn about it - http://www.amazon.com/Techs-Motorcyc.../dp/0760331405
