complex numbers in polar form: the angle θ can be in degrees or radians, so do I have to change the mode on my calculator every time?

...anyone? Yes? No?...

When you get to any kind of trig problems, especially polar coordinates, it's best to have your calculator set to radians.

The best thing to do is memorize the unit circle, or have the degree to radians formula handy, most problems in a math book will deal in the standard easy to remember stuff.
