A tip I learned is you always want to shoot on the lowest ISO as you possibly can to prevent noise. To prevent blur and shakiness use a tripod, or a beanbag, or something else you can use to stabilize your camera.
As for your shutter speed, you should never have to shoot in 1/2000 for much of anything. I would start out using P-mode or Av, which is aperture priority. Look around here, as well. Once you think you have a firm grasp on what settings to use, go out and start setting your own in M, which is manual exposure.
Also, something else to think about. When taking a picture, ask yourself, "would I want this as a print?" or "would someone want this hanging on their wall?" also, ask yourself two very important questions: "Why should I take this image?" and "why shouldn't I take this image?"
Also, once more, when shooting, you tend to shoot more the emotion and feel of the scene. Not the scene itself. So try to capture the mood other than the actual scene itself. If someone feels as though they want to be in your picture, no matter what it looks like, or if it makes someone feel a sort of nameable emotion, it's a good photograph and has done it's job as art. I hope I've helped? I'm quite new myself.
Anyway, keep at it. Keep posting and asking for CC. You'll get better and by no time you'll be posting decent images that eventually will turn into works of art some day. Practice makes perfect - I've been improving my photography bit by bit by just going out, shooting, and posting them here asking for CC. I know I haven't been active recently, but I've sure been lurking. And I mean sure, the critique was harsh, I sometimes felt attacked, but as a newbie you just feel ganged up on. But it was very helpful in the long run. I'm not the greatest, but I'm sound with saying I've improved since I've joined in this short amount of time.
Note:
Owning a good camera doesn't make you a good photographer. It makes you the owner of a good camera that wont be used to it's full extent. Start off with a simple point-and-shoot camera (which I believe you have now. a Hitachi twelve mega pixel, right?) to get to know the settings and different features. I mean, I started out with a four mega pixel DCM-42 Gateway point-and-shoot camera. While most cell phone cameras have eight mega pixels.
