Some components have standby modes or other design provisions which result in some of their circuitry always being powered up, as long as they are connected to ac. Also, anything that can be turned on with a remote control would have some circuitry always powered, so that it can respond to commands from the remote.
Also, if the power or lightning surge is sufficiently strong, it could conceivably jump across a component's power switch.
Solid state components are more susceptible to damage than tube components, not vice versa. Although keep in mind that modern tube components often contain considerable amounts of solid state circuitry in addition to the tube circuitry.
Yes, I would definitely unplug from the wall during potential thunderstorms.
