Re: mast bend
Randomly easing standing rigging is as likely to create new problems as it is to improve the situation. Because the mast is keel stepped, you need to sight up the track and try to see what is going on. If the mast gently curves aft, then you might actually need to tighten the forestay.
But before you do anything you need to try to figure out what is going on by methodically checking the mast step, partners, shroud and stay attachment points, and whether there are cotter pins in all of turnbuckles.
The key is to get your eye next to the mast track and carefully sight where the curvature is actually occurring. If the curve is a smooth and even curve then it comes down to moving the masthead forward a little which can be done with either tightening the forestay or easing the backstay a little depending on the adequacy of your headstay tension. But it you have an S curve, which is more likely If you see a tight curve near the top of the mast, you need to move the mast head a lot more, and that will require loosening the backstay and tightening the forestay while paying attention to the rest of the the rig tune.
Lastly, if the bend is really in the last 8-10 feet of the mast, then the spar needs to be inspected because that sounds like the spar itself has been damaged since there is nothing in your rig geometry that can cause that benignly.
