Camera actually has very little to do with "good pictures". Most good photographers can take awesome pictures with a crappy 35mm anyday. They take tons of pics using different camera settings of the same thing, and choose the best of them.
The trick is the match the settings on the camera to the situation you have in one go (or know some general rules). If it's a close macro shot of a leo, use alot of bright light in the area and use the flash for needle sharp detail. No flash shots in a dark room is asking for trouble.
If your camera has apeture and shutter speed options, experiment from medium to fast shutter speed and all apetures (probably the wider appetures will give you better results in macro shots).
Depth of Field (DoF) is a very important concept in photography. If you take a picture and only a small part of it is in focus and the rest is out of focus and blurry and you lost alot of detail, it's a bad pic (some people use this to great advantage though). Wider appetures give you lower DoF while small appetures give you higher DoF, again, I don't own your camera and each camera is different, so you have to experiment and find what's best for the situation.
