You've probably worked this out for yourself by now, but i think the trick here is to pick an image that looks good at 800x480 and then use PSP or similar to squish it to 256x256. The HD seems to resize the image to something acceptable when it renders it.
Worked for me anyway. Having said that, the image quality isn't fabulous - decent but not spectacular - from what looked to be a good starting image, so maybe I'm doing something wrong - I'd expect a decent image on a screen like the HD's.
Any other suggestions from those that have already replaced backgrounds?
