Don't stress, but also try not to be too breezy about it, either. It takes work, and real effort. You, of course, are not me, but I took a few months off everything Tarot related just to study Qabalah (which really isn't that difficult once you get in the spirit of things). My method is simple, I don't skip ahead unless I understand. It's taken me about a year and a half to get to Adjustment, but it's been worth it.
Be warned, though, Qabalah is the deck's backbone. I tried to put it off as much as I could, but there is no getting around it. Ultimately though, I fell in love with it.
Oh yes! I have what could only be described as a very shallow familiarity with the Qabalah, after reading about it (and not understanding most of it ) over a period of a few years. My thinking before was that I should be more knowledgeable regarding Qabalah, before beginning the study of the Thoth.
But then I decided to just jump in, do one read through of the Book of Thoth, and then go back and take each card slowly. It will take many years, if ever, to truly "understand" it, but that is really the beauty of it.
There will always be more to learn, and as life experiences color everything, even what was "learned" is likely to be re-interpreted! So my vote is to jump in and get started, and begin the process.
Also, my attention span is such that I doubt I would be successful in taking a few months away from tarot to study the Qabalah - I am envious of your drive. (Seriously, I am not being sarcastic. I tend to worry how things come across in posts.)
