Button debouncing.
Isn't the logic inverted for the button? I.e. if it is pressed, then the value of PIND should be 0. When not pressed, it should be 1.

Battery Monitoring?
How about this circuit? When the MCU has power it can turn on Q1 through R2 which turns on Q2 so that the voltage across R3 becomes Vbb (the battery voltage to measure). The MCU'...
