Nothing in those settings particularly likely to cause a problem - just background noise evident in the poor lighting conditions - longer exposure / smaller aperture might have been better.
One common misunderstanding about 'noise' in digital imaging is that shorter exposure times will result in less noise. While technically this is correct, in practice longer exposure times result in a more even distribution of the noise, thus although still there, it is may be less evident when longer exposure times are used.
Obviously, long exposure times are not possible when shooting moving objects so compromises must be made on the aperture / ISO setting when shooting these in poor light.
What might be useful (if the camera allows it) is to bracket exposures over a series of times / apertures when shooting and select the best image.
If noise continues to be a problem, I really would reccommend 'neat image', I was truly astounded by how well this worked.
[EDIT]
Just to confirm I'm not talking boll**ks (as I sometimes do!), and get a bit of practice driving my new camera, I thought I'd take a few test images of a dark subject in dim light.
A selection of the results can be viewed at
http://dennis-lance.fotopic.net/c975808.html. This confirms how apparent noise levels are reduced when exposing for longer times and that just leaving the camera on auto can still provide near optimum results even in difficult circumstances. Surprisingly, the image on the night setting was completely underexposed and no detail whatsoever was visible.
I found this exercise a useful learnng experience.
