The parking brake will not cause wear to the brake pads, assuming the car is stopped. With your car stopped, stomp on the brake pedal all you want - no wear.
I park my EL with the handbrake pulled tight and the car left in 1st gear, because if I forget one of those, the other will prevent me from finding my car in a location other than where I left it. On a steep slope, you may have to really yank the hand brake, but it should stop the car unless you parked on a ski hill.
