Holding it steady is my problem right now, I don't like the shutter speed on the thing.
Just play with it is the best I can suggest. Use the macro mode in stabilized mode, try the sport and under water presets.
I am finding the WB is pretty good as is, and turn off the flash.
I have yet to master it myself, but practiced a little over the weekend:
Green Slimer and Cardinal
Pink Lemonade
Milli
Oregon Tort
Lime in the Sky
Blue Matrix
