Even with a wool blanket/pillow case/hat, the locking process may only be accelerated by a few weeks to a month. Is one month really worth it? Wool does cause tons of frizzies. They'll look really messy for longer than if you just let them be. Not to mention that when you use wool, you have to separate much more often. And messing with your locks that much can make you accidentally take some out. It's just easier to let them be and only separate occasionally.
As for sea salt. The max time you should ever have it in your hair is 2 hours. Minimum is to just use it in your wash. You don't need to let it set. I choose to let it set because I have a few brand new babies on top of my head. But when you're as far in as you are, you don't really need to
