Wow, great knife to start with. I have the CQD MK II (smaller, window breaker instead of secondary blade), and I love it. cpirtle and Eric Blair and a couple other guys around here have them too and love them. Definately a great folder.
For sharpening, a lot of people recommend the Spyderco Sharpmaker. It's easy to use, but it works a little better than systems like Lansky. Plus you can sharpen serrations, recurves, etc more easily.
One other option, though, and one I recommend, is to pick up a decent benchstone, and practice on a knife you don't care about or can replace cheaply. I practice on an Opinel. There's nothing to compare to freehand sharpening. After awhile, all you'll have to do is sharpen it up really good one time, and then just strop it from time to time to bring back the edge.
