Crank no start

Car listed above is a Stationwagon. I had drove the for a good while and then when I parked to go inside it didn't start back up. A while back I had a misfire problem with the car and it was misfiring on all four cylinders and replaced all four spark plugs and coil packs and the misfiring stopped. The car also would shut off sometimes while idling if I were to drive into a parking spot and sit for a moment it would rev up on its own and then stall out and quit running. Someone said that it sounded like my alternator was going bad but this was before it stopped working. Now the battery is brand new it had four new spark plugs (before oil in my spark plug wells caused them to foul out) and coil packs but the spark plugs have been fouled out from I think oil got into them because of what I believe is to be a bad/cracked valve cover gasket but I have yet to have time to check. Help, I know very little when it comes to Volkswagen. I want to say I have narrowed it down to 1. A possible bad alternator. 2. Bad spark plugs and oil in the spark plug wells. 3. Bad/cracked valve cover gasket. 4. Maybe a bad starter as well. And I am not going to rule out fuses as well. I don't have the diagram for it so figuring out which ones are what is a problem. I am not sure but these are what I think may be wrong with it maybe. Please help. I have also left a video of me attempting to start it.
