Sounds like you have a few issues occuring here.
I would have the engine and transmission mounts checked for any issues.Any issues found will need replaced.I would have the fault codes checked with a compatible scan tool that will plug into your model and can communicate with all computers to see what codes are set.Once this is done any codes set will help diagnose the harsh shift as well as the no start here.The no start may be caused by the vehicle security system.In some cases with a good battery connected locking and unlocking a door will reset the security system.In other cases a dealer may have to reset/reprogram the security system.
If the gas pedal was stuck this can be an issue with the pedal itself or in some cases on cable driven systems a fault with the throttle cable needing replaced or carbon build up in the throttle body needing cleaned.This will have to be checked into further to locate and repair this issue here.
