Oh dear dmouse...so very sorry you are going through this hell!
From my hellish experience in divorce, I agree wholeheartedly with simplesally's post to "get your ducks in a row" especially financial!!!
Do you have any JOINT accounts? Credit cards, etc.? Time to remove her name on anything that is joint NOW. If not, good!
Vehicle titles, insurance policies, etc. ad nauseum. Sorry buddy-but it sounds like it's time to take action and really protect you and your own best interests, and when it comes to $, you CAN prepare.
I am not nor ever have been a JW, and I have "apostate materials" (much like the what you had in your house) in my home. My JW hubby has his own book shelf in his closet in a second bedroom. Although I have wanted to burn the entire contents of it, I would never do that or remove any of his WTS materials. They are HIS and we both thankfully still have enough respect not to do something like that to one another.
BTW, when he first told me that he was going back to get reinstated, I put him on the couch for a few nights, and then told him I could not do that as it was HIS bed too. If one or the other spouse is out of the bed, they are soon out in another room, then very soon out of the HOUSE.
Whatever you do dmouse, TRY NOT TO TOUCH OR THREATEN HER EVEN IF SHE PROVOKES YOU. Self control is your greatest weapon friend! She could slap a restraining order on you in a heartbeat, and you won't be able to get most of your things out of the house at all ( depending on the state).
Sorry to sound so morose, but been there, done that, threw away the T-shirt!
Prayerfully, mobbie
