depends how much work your gonna be doing to it. if your confident with filler then remove the strip if you want it gone, myself ide leave it there for the handle.
as for the boot popping, you can either fit a solenoid so it pops itself from a fob or you can just wire up the catch to a popper inside the car. maybe to by the backseat. pain in the ass to get into the boot, but its cheaper.
