I think we just need to get you a camera with more than 2mp's and a modern sensor and processor. I think you'll surprise yourself. Even with that camera, your pictures are fairly decent.
You should consider dropping a couple hundred bucks on something like this: http://www.amazon.com/Canon-PowerShot-SD4000IS-Digital-Optical/dp/B003L77Y5S/ref=sr_1_1?ie=UTF8&qid=1295842991&sr=8-1
It's a full auto point and shoot. I just bought this exact camera for my wife and it does an EXCELLENT job with pictures. Easy to use too. In fact, it's so good in low light that often, it doesn't even fire the flash when another camera would, which should keep colors from washing out. That's not to say that the flash never fires though.
If you're interested, I'll be happy to snap a few boa pics with it (when she gets back in town from visiting her parents) in a setting like you normally use so you can compare them to yours and see if you think it's worth it. Just let me know man
