Adopting basket cases can be fun. There are numerous youtube video's on disassembly of a S&W, and the Jerry Miculek video is one of the best. The Kunhausen shop manual is indespensible in tearing down and working on S&W's.
I can't figure out why any missing side plate screw would have anything to do with how it may cycle. Sounds more like the double action sear is stuck, possibly caked up with dirt? Maybe just a good cleaning might do wonders? Good luck, keep us posted.
