How hard to replace are those blown fuses ?
jmc,
If the lens works on someone elses Pentax the chances are that the contacts are dirty on either your camera, or the lens. It doesn't take much dirt or tarnish to cause problems.
Just scrubbing them for a moment, with a toothbrush or whatever people use might just fix your problem.
If your camera isn't under warranty, and that doesn't help I'm going to suggest that you bring the camera into a local shop, where they can repair it for you. The chances are that there isn't much wrong, so the repair cost shouldn't be bad.
Unless you've taken electronics courses the chances are that you'll make things worst rather than fixing things
