What Akali said, if you weren't getting new forks. As you're getting new forks, you might as well get a new headset. And if you're going to DIY, then you need a cup remover (or a bit of old pipe or something and mallet), a crown race remover (or screw driver and mallet), and cup puller (or mallet) - (warning: the alternatives (in brackets) may damage components).
Re sawing the steerer tube, it's not really all that scary. If you're happy with your current setup, just saw the steerer to the same length. If you're really not confident of your sawing, there are guides available to maintain a straight cut, but they're not necessary provided you can cut within I'd say half a centimetre tolerance. Hacksaw and file is all that's needed there.
But if you don't want to get the tools I mentioned for dealing with a complete headset replacement, you might as well get your LBS to do it.
