In your picture #7, the pin through the top of the boom should be through the grommet (reinforced hole) in the sail; the bolt rope on the foot (bottom) of the sail should be in the track on the boom. Your main halyard should be pulled tight to get the top of the mainsail higher to eliminate the wrinkles vertically.
The outhaul (photo 11) should be tighter to pull out the wrinkles along the boom (after putting the bolt rope in the track).
In picture 1, that pole inside the boom doesn't belong there, and if you want to use a pigtail off the backstay to support the boom when not sailing, it should be fastened to the backstay well above the boom so the the load on the backstay is more vertical (or more nearly parallel to the stay). At present, your attachment for the boom is pulling forward on the backstay, adding to your mast bending problem.
If you can adjust your rigging so that your mast is straighter, the above changes should get you a much better mainsail shape.
Good luck! -Paul
