You've got it all right mate.
1 screw in the door handle, 1 screw in the electric window control, and 1 pop screw at the upper front of the door trim. Lever a screw driver behind the electric mirror sail (back of mirrors) and remove this. Then get your fingers behind the area where the pop screw was and
gently lever it towards yourself while moving your hands down towards the ground. FOllow the door trim towards the speaker grill then around towards the small light, then up towards the lock. You should find the little clips holding the door trim onto the door will pop out. then just lift the door trim off the window sill and disconnect the light and you're done!
The white dots show where the clips will be behind the door trim
