I have a simple little sony cybershot.
I use a custom setting that I programmed in, but basically use macro like said previously, NEVER USE FLASH, and see about making a makeshift lightbox. Mine is two pieces of white bristol (the "floor", and background), and a desk lamp from ikea with a movable arm that I can re-position to get the light where I want it.
I also do touchups in photoshop real quick, which are usually just doing an auto-adjust on tone and color to get the image as close to real life as possible (or to remove yellowing from indoor light), as well as adjusting brightness and contrast. I'm a night-owl, so I never seem to take pictures when the sun is still bright LOL
