Keeping in mind, I don't read much for other's, just myself.
I study wide and read narrow. That's means it is fine for me to study deep and high, but when it comes down to a reading the typical divinatory meanings such as DuQuette's Understanding starting on page 278 may be all I use. If I have trouble getting that pragmatic after my head steeping in the esoteric stuff, I like the General Character of the Trumps as They Appear In Use (Book of Thoth pg 253) and I notice DuQuette using them at the beginning in italics in his Major Arcana Trumps section. Those help ground me a bit without feeling as if I lost the essence of the card.
I find journaling the most helpful. I just journal what is going on each day and then pull a card. I do not pull a card and then journal. The magic seems to happen the other way around. It never fails that the deck has heard me and responds, though it might take a day or two to understand that it has. This is how I gained my trust in the deck.
It can be very overwhelming. The Fool and the High Priestess gave me much trouble. I've been know to overlook them and pick another card in the beginning. Or draw a second card to narrow the field on those two.
It is a lot to remember for me and I have never been one to sit down and read for someone ad lib. I usually will take my time and do an email reading, if someone asks. This way I can stick to the facts and monitor myself so I don't get to "out there" and also so I can be more reflective and less reactive.
You will find you own way though if you stick with it, I am sure of it.
