Hi queenofcups - first of all welcome to AT and the Thoth Forum.
I am myself quite new to the Thoth deck and am still in realtively early stages of studying this interesting deck (which will no doubt go on for quite sometime!). However there are other AT members who are far more knowledgable in this area than myself.
As a suggestion you might like to start a Thread in this forum with the Bardo States as a subject and you may have others jump in who have information about this.
Please also feel welcome to join us in the individual card study threads if wish, as it would be great to have someone with your experience with this deck to provide added insight and ideas. Look forward to reading your posts.
