Could you post some sample pictures (with exif data, jpges out of the camera will have this)? This would help in analyzing the problem.

At ISO 6400 (that is what the EXIF data says) wouldn't this amount of graininess be expected?

To me the photo looks slightly out of focus (what were your focus point(s) on?) as well as iso6400...which is pushing it or perhaps already pushed it to a noisy level inherent to the sensor.

Fokuserte på statuen,har prøvd alle ISO innstillinger med andre innstillinger.Synes det er for mange innstillinger og holde styr på for og ta bilde,må hele tia huske på lysinst og lukkehastihet,blir det brukbart på et bilde,blir ikke det på neste om en tar bilda av noe annet,da må en stille igjen.Vist det er sånn,da synes jeg det blir for tungvint.

There is a steep learning curve if you move from point and shoot cameras to DSLR cameras. Try using the "auto" setting first, it is like point and shoot. It will take time to learn all the other modes and what you can do with your Kx. You just need to be willing to learn and experiment, and read the manual a few times, it covers all the basics. The Kx is a very nice camera once you know how to use it.

This image was shot at iso50 and better lighting as well as a subject at a more linear focus plane....try shooting the same image with your Kx at iso 100-800 and see how you feel.

The grainy appearance is due to the high ISO (6400) used. With the built-in flash auto modes e.g. "AUTO PICT" in combination with low ISO (200/400) should work best most of the time.

Low ISO = best picture quality
High ISO = noisier picture, but you still get one in low light

Looks slightly out of focus

I also bought a K-x last month and the auto focus needed adjusted. Now mine is just great. Play with the camera until you can you can tell if it does need adjustment. You may want to check out the instructions for getting into the debug mode to adjust it. Just do an internet search for debug mode Pentax K-x.

LOL. One step at a time please! The OP needs to make sure he understands the basics of DSLR shooting before going straight into geeky stuff like AF adjustments using the debug menu!

The issues raised by the original poster are common ones for people transitioning from point and shoots to DSLR's. The main issue is that point and shoots - due to their tiny sensor - have massively more depth of field than DSLR's, meaning almost everything is usually in focus unless you make some huge blunder like move the camera too much while taking the shot. DSLR's are different from point and shoots with regard to depth of field considerations, and these differences need to be understood. The article below maybe useful for that:
Understanding Depth of Field in Photography

In terms of the posted image, the shot is noisy due to the high ISO used ('I thought, higher ISO sharper picture'), a situation that could have been improved by shooting with a lower ISO and using the flash, or otherwise improving the light on the scene.

The shot is also 'out of focus' if the focus target was the statue, but clearly in focus if the focus target was the shelf on the back wall, a situation that could have been improved if the photographer used a smaller aperture to obtain a deeper depth of field to ensure that more of the elements of the scene were in focus. His result could also have been improved when shooting such a cluttered scene with many potential focus targets by using spot AF to target the AF with more precision. As it is, it looks like the AF locked onto a nice high contrast area of the frame (the shelf on the back wall) rather than the dark statue in the foreground. That's not the camera's fault. It can't read the photographers mind about what the important subject in the image is.

You are right rawr, first things first.
