Number 2 is real simple. Simply adjust the lock latch located in the trunk. You know the loop that the lock connects to. You loosen the torx screws and adjust the latch up or down as needed.
The rest I am not sure of... Number 3 might be a loose connection in the center console. If you can jiggle the E-brake handle, then that is most likely what it is.
I would like to know the answer to number 4 myself.
