If the screws you are talking about are the three on the bottom plate they are quite small. You'd need to drill holes for a screw extractor. You'd have to make that -perhaps from a small (2 mm) square file? - without destroying the threads. Of course it might be possible to re-tap the holes to 2 mm, but I wouldn't like to try that. The original screws are 1,7 mm in diameter with a threaded portion 2,5 mm long. Is there nothing left of the star at all? Could you not get a sharp single bladed jewellers screwdriver (2 mm) into what remains? To drill a hole for a screw extractor would be a very difficult job.
When you do get the plate off how are you going to put it back? You'd need to order new screws from Pentax. Incidentally you may be on the right track. I think the mechanism that links mirror, shutter and cocking lever is simply sticky. Most of this kind of trouble comes from two levers on the bottom of the shaft not doing their job. Simple local CLA may be all that's needed. Off course if the shutter is jamming its and entirely different kettle of fish.
