Another Couch to 5K believer here! Fantastic program. You will build up gradually enough to avoid injury and to figure out your best running style.
For your iTouch: you can get the actual C25K app, which allows you to use your own music (or podcasts) and prompts you when to run and walk. I especially liked this on the treadmill, b/c it was easy to see how many seconds left in a walk or run segment. It also works for your armband, with voice prompts - you don't have to look at it.
There are also a bunch of podcasts that take you through the program. The music in a lot of these is a kind of techno-pop that has the appropriate beats per minute, but that I found really annoying. However, the Chubby Jones podcast I liked much better. Narrated by a funny, upbeat woman named Mia who encourages you along the way, with a real mix of music. She'll tell you "get ready to run in 30 seconds" then countdown the last ten, and also tell you when you're almost done running. I found her very motivating. She also has a 10K training program, if you get hooked on running.
If you have an iPhone, I highly reccommend the RunKeeperPro app. You can program your couch to 5K intervals into a training program, and get voice prompts to run and walk. It also has gps tracking of exactly where you are running, and online support so you can see a map of your run, with pace and elevation data. Really really awesome for outside running, and at $10, way cheaper than a Garmin running watch! For an iTouch, get the free version - it doesn't have GPS capability but is still a good app.
I've been a fitness walker for years and years, and can't believe how much I've come to like running. And always thought I was in good shape, but running has changed my body dramatically. Good luck to you and let us know how it goes!

) that the World is not set at a 0% incline. I run at a 1.5% incline (a 1% incline is about the same as a "flat" surface outside). I do recommend that before you do a 5k (or any race) that you get some outside runs in at least (if not all of the time).
I still run out of battery every once in a while!!
