Learn correspondences. Like the symbolism of colors and the properties of herbs and gems. Also look into ceremonial magic and the basics of ritual. I would also look into how to construct an altar. It doesn't have to be path specific just add visual aids to help you focus while casting.
You can find gem and herb properties here
Basics on altar construction
Good general info
I also suggest a book titled True Magick by Amber K.
Good luck and may blessings find you.
