The only place to find the exploded view of the steering column is in the service manual. The ignition switch and the key cylinder in it are both serviced separately. You don't have to do anything to the column to fix them.
There's two types of shift indicators. One has an adjustment screw under the middle of the column on the right side. One just has a cable that attaches there, then the pointer is on a slide. It adjusts automatically when you shift to park and first gear.
The transmission staying in second gear is "limp mode" that allows you to drive slowly to a repair shop without needing a tow truck. The only way to get it out of limp mode is to turn the ignition switch off and restart the engine. There will be a diagnostic fault code in the Transmission Computer. That will indicate the circuit or system that has the problem. If you start the engine, shift to drive, and it immediately starts out in second gear, that is usually caused by a sensor failure or some other electrical problem. If it starts out in first gear, up-shifts normally, then suddenly bangs back to second gear, that is typically caused by clutch plate wear that is too excessive for the computer to adjust for. A transmission specialist can verify that by reading the "clutch volume index", (CVI), on a scanner. That is a set of four numbers corresponding to the number of ccs of fluid it takes to apply each clutch pack.
