OK, your mast tabernacle looks great. Not compressed into the deck at all. I think I see why your turnbuckles are nearly closed but I'm not sure enough to say here.
A suggestion for you: Put tape on the screw threads right next to the outer ends of your turnbuckles before you go sailing again. IF your stays go slack again, check to see if the tape is still against the turnbuckles. If there is a gap between the tape and turnbuckle, your turnbuckles are unscrewing and need pins through the little holes in the turnbuckle screws. The closed turnbuckle on the starboard side should still have the locking nuts against the turnbuckle body.
The only way to figure this out now is to GO SAILING!!!! Enjoy the day. Check the tapes when you return to the dock.
About the bend in your mast, I say ignore it. My brother drove my 16 footer under a power line and bent my mast a bit but it never affected the boat's performance. It took several washings to clean his swimsuit, tho.
