Note: All this refers to Rider Waite Smith decks only:
I am new too and new here. I have only been learning Tarot for a couple of years even though I bought by first deck, Mythic Tarot (original) around 1995. I bought my Universal Waite Tarot a couple of years ago, which I love and then collected tons more. Another great beginner deck is Llewellyn's Classic and/or Beginner Tarot (sharman-caselli). They are RWS clones. I didn't start with my Mythic deck because I didn't want to have to learn about Greek Mythology on top of learning Tarot. In the beginning, I would suggest staying away from Themed decks (pagan, celtic, etc), just for that reason.
For a long time,I held off on actually laying the card in a spread and reading. I didn't feel like I was ready because I didn't know the meaning of each card. Huge mistake. I learned so much more and faster, being hands on. So please don't make the same mistake. Get in there, right away. You will have to refer to your books/sites to get the basic meanings for the card, but that is how it's going to sink in. Basic meaning are ok but you must come up with your own and you will do this by using your intuition.
Other advice: Before you get into the astrological correspondences, Kaballah, etc (but not before you learn the elemental dignities). I would really look at the cards and pick out all the symbolism within each image. It is amazing what you will find. I researched this symbolism and their traditional meaning and it blew me away! I promise, each time you look at the cards (at least initially speaking) you will find something new. About 5 months after I started, I noticed the quilt in the 9 of Swords. I never noticed the zodiac/planetary signs embroidered in the blue squares. Crazy.
Great Beginner Books:
These 2 have exercises throughout:
21 Ways to Read the Tarot - Mary Greer (one of the best books to learn the cards)
Tarot 101- Mastering the Art of Reading the Cards - Kim Huggens
(this has the card meanings and includes common symbols)
The Secret Language of Tarot - Wald and Ruth Ann Amberstone (if you want to dive deeper in the symbolism, this book is great)
The Ultimate Guide to Tarot - Liz Dean (I love this book)
Taking the Tarot to Heart - Mark McElroy (although it only refers to readings on love, it's a great book of in depth reading examples)
More Advanced:

And a little tip: Fool's Dog apps offers many Tarot deck app, some(not all) of which include their companion books. So for 4.99 you're getting a good book on line along with the card images. Classic Tarot (Llewellyn's) does include the book by Barbara Moore and it's really good. I think. Precise and to the point. Beside the book, It's a great way to compare decks (which help when you're first starting) without having to commit and spend 3-4xs the amount.
And like others said, definitely start a journal. If you want to do a digital journal, that's fine. But if you are going to hand write in a journal I would get a 3 ring binder and index marker. This way everything can be organized well and it wil be easy to find what you're looking for. Also, writing/typing helps for meaning to sink in. But, again, like other said, don't memorise, they should be your own meaning and there is no right or wrong in Tarot.
Hope this helps. Welcome to AT and Tarot. Good Luck with it all.
