I have the same cam. Things get improved a lot, once you get the hang of the modes like "M, S and A". Also for taking a still shot with zoom above 8X, a tripod is a must, or there should be enough light around to use higher shutter speeds.
You just need to balance the amount of light coming onto the sensor.
iso: lower iso> lower light (but sharper) - use at bright areas
higher iso : much more sensitive to light but at the cost of sharpness (noisy image) - use on dark lightings
Shutter speed: Not just decided by whether you need to capture a fast moving or slow moving object. It also decides how much light falls on sensor (actually its the period, but same effect in real)
higher speed like 1/1000: low light sensitive. Use it for bright occasions, and object is moving fast or is zoomed in- but the cost of aperture.
lower speed like 1/10 or 1/30 : use when object is still, hand is still (or a tripod), or available light is low. (best results is obtained by using slower shutted speed and a tripod, even for macros)
ultra slow shutter speed: 1 sec to 60 sec: use for ultra dark situations like night shots. A tripod is a 101% must. You will be amazed with the amount of light on the final pic.
Aperture: regulates how much light enters the cam. Also decides the field of focus
low aperture: eg. 2.8 : low fild of focus, but max amount of light enters. [can be used to focus only one subject and excluse the background at some distance by making them out of field of focus.
high aperture: eg. 8.0 : max field of focus. Almost entire objects are focussed (not entire
), but only allows feeble light to pass through. Use it at extreme high bright scenes, or with a tripod and longer shutter time [low shutter speeds].
these are some tips. Now truy out the "m" mode and try out these setings. You will learn in less than 3~4 days, and you will know what setings to use, when you view a scene with your eye.
