Bill,
On the fuzziness, one mistake some folks make is to leave the camera on total auto, that makes the ISO setting automatic and the camera will raise the ISO to get "lower light" shots, set the ISO to the lowest ISO setting you have (normally 80-100) on most cameras. Then only move it off there if absolutely necessary. That reduces "grain" to a minimum. The other main causes of fuzziness are 1) hand held in low light situations resulting in "camera shake", 2) Low Resolution, make sure your camera is set to the highest resolution possible, cameras allow you to reduce the resolution to get more shots on a card set it on high, additionally fill the frame as much as possible remembering that you need a small border around all sides to prevent cutting off sections.3) Camera doesn't have sufficient resolution, normally depicted in Megapixels, most modern cameras (point and shoot) are in the10-12 MP range, I use an SLR with 15MP but the newer ones are going to 18 and some of the really high dollar ones are over 20MP. 10-12 is sufficient for very sharp pictures.
One recommendation for the lighting is to use a Photo Light Box, you can get as extravagant as you wish but you can significantly improve your photos with a simple one that is very cheap such as the one depicted in the link.
Hope this helps, there is a ton of info on the internet about photography.
