Stopping down f8 is generally good advice for just about any lens, but especially the kit lens, which does not have very good border to border sharpness (particularly at wide focal lengths). Get the camera on a tripod as well, and try to find something with contrast to focus on.
If you do any panorama stitching, shoot somewhere between 28 to 35mm, as the kit lens performs at its best in those focal ranges, and combined with the stitching you'll be able to create images with a very high resolution.
If you get a polarizer, be careful when using it at the wide end of your kit lens, and don't use it at all for stitching shots. In the 24 to 55mm range, a polarizer is highly desirable for darkening and enriching blue skies. The kit lens struggles to render dark blue and needs all the help it can get.
