Man that could be a whack of different things.... I'm thinking MAF, Vacuum leak or possibly a bad ignition coil. Disconnecting the battery doesn't normally hurt anything at all and if the PD said "shame on you for having disconnected the battery" he was probably just being a smart ass lol. The throttle body calibration should be done after the battery was disconnected but the car should run fine without doing it and even if you don't do it, after driving a while it will calibrate itself (just takes longer).
I would pull the connectors to each coil one at a time to see what happens. If you pull one and it doesn't have any effect then you either have a bad coil or a bad plug.
I've seen these things fail and cause issues and not set any CEL. Bizarre but it is what it is... It probably had nothing to do with your bulb change, it was most likely just a coincidence.
A failed coil will usually cause shaking to what you described....
I hope you find the gremlin - good luck.
