Someone tell me if this looks like a good way to pull an image and resize from database with minimal degradation. If there is something I could be doing that will increase the quality of output let me know.

It's just the nature of image scaling that there is going to be some loss of information. java.awt.Image has a method, getScaledImage(), which gives you some control over the quality of the scaling through the third parameter, hints. Unfortunately it does not return a BufferedImage, so it is still necessary to create a BufferedImage instance and paint the image onto its Graphics instance. I don't know if this would give you better or worse results than your current code. Try it both ways and compare the results.
 
It is sorta covered in the JavaRanch Style Guide.
