It sounds like you have done the right thing. Tarot are very deep and to be honest if you look at all the different meanings and spreads it can be a bit daunting.

My advice is to practice on friends at first. Just to get your confidence.
Is there a book with them ?
To show you the meanings.
Learning them online is good there are some great resources out there which show the meanings of cards and learn about them.

I have never looked at the numerology side of it but as i say the tarot is very deep and every card has a number.

Its what works for you.
The more you practice the better you get.
When you look at the cards and know what they mean there is a way of tuning in.

Being open grounded and protected is the best way to read them. Relaxed and meditated. Chakras cleansed grounding and protecting too. Defiantly work with your guides too.
They give me my extra information.

But one step at a time.

Just get the cards then you get your meanings book for what they mean and practice on a friend.
The rest will just come.
I am not the only reader on here and i am sure there are others that can give you different advice but its how i started.
Learn what they mean use the book for reference at first till you feel comfortable working without it.

Practice and then you will flow..... its not what the cards mean it is what comes with them.
I use the cards as a tool to see. Everyone is different.
Enjoy your journey with them!
