Ok let’s look at the problems one at a time
cab lighting is LED, so I’d try a factory reset before condemning the circuit. If no joy on a reset, the engine will need to be opened up to examine this fault.
whistle steam is powered by the Aux smoke switch. Be sure that is on.be sure there’s smoke fluid in the reservoir, the whistle smoke is separate from the main smoke!! If the engine has sat for a long time, sometimes sliding the switch back & forth a bunch of times can get it to work again. ( if that’s the problem ) take the tender off the track, you can operate the whistle without the tender, and you should faintly hear the whistle steam motor. Blow down the whistle s hole to clear any possible air locks.
main smoke stuck on via the switch. more than likely is a failed switch in the on position. You can turn off your smoke via remote for the present, if need be. I would just leave it in the on position for now.
