You are asking too many questions at once.
So, you're normal, without any ESP, etc, so are all Wiccans.
Peering into a crystal ball, or a dark bowl of water, focuses the mind, nothing else; oh, and forget all the nonsense of collecting it at midnight during the dark of the moon, intent is what is important.
You don't read the Tarot, you learn from it, the Tarot is wisdom, not prediction.
Satan is a part of Judaic based religions, it has nothing to do with northern and western European Old Ways, except for application to those ways by religious leaders grasping for power.
If a god cannot forgive, it is subject to emotion and therefore, imperfect.
If you wish to follow the Old Ways, go ahead and do it, you do not need to be part of a coven or group, solitary is fine, you don't need things from exotic places and if something calls for a gold candlestick, paint a wooden one gold, although even that doesn't matter. It is worth remembering two things:
a) paraphernalia, chants and spells are only for focusing the mind, they have no other power.
b) and harm none.
