It's almost like everything isn't getting quite enough power to fully operate at first and then after everything warms up it's all fine again.

that sounds like a bad ground. u should grab a meter with long extensions and measure the resistance from battery ground to the ground on your stereo(and alternator ground to your batt just to make sure it's good) and panel lighting/controls. there are points on the car that develop poor continuous body ground so jumpers are added to continue a solid path.
the service manual has the ground locations for devices in it so it would be ez to find the stereo ground and see if it shares the same connection with the other devices your having problems with.
