2.) Again, Don't start the car, You'll cause engine damage by starting it and all hopes for a (cheaper) repair are out the door at that point.
1.) Light bulbs don't compress and change driveline alignment, thus improving vibration. And if you don't like the dark and know the burn time on the bulb, then yes, one can change it before it fails. This is called preventative maintenance. Commone in critical production industries.
2.) Even after the repair, you don't start it until you have inspected the chain guides. Read her via searches, starting with the Articles Forum. If you have original guides at 200K, you are the champion. But I am betting if your guides are original, there are pieces in the sump. Another reason to combine the jobs.
