In these sort of photos, practice, and paying attention to the setting you choose and the reuslts pay off.
Use Manual exposure and Aperture, there will be some trial and error, but this is necessary.
Get a tripod or a beanbag, or a Joby flexible tripod, anything to stabilize the camera as much as possible.
Go for a lower ISO, which means a longer exposure time, results are improve by stabilizing the camera as above.
The other benefit of a tripoed is that you can stop down to f8 or f11, many lenses, DA 15, DA 21, FA 77, among them, make some awesome starbursts of lights when stopped down.
If you are interested
I have an album of night shots with lighting using either a K-5 or a K-1, you can try my settings out
Good luck, I look forward to seeing your pictures.
