Hardware - you'll need an adapter on your scanner.
Software - Are you using Windows? if so, a free package like the demo version of PaintShop Pro would allow you to manipulate the images. If you're using a Mac or Linux machine, try using Gimp. You shouldn't need to buy any software - there's plenty of free packages that'll do the job. If you wanted to invest in imaging software for Windows, I believe there's a scaled down version of Adobe Photoshop called Photoshop Elements.
