i think you're starting off on the wrong foot. are you starting a new spiritual path or just want to cast spells? if you wish to convert to Wicca or some other Pagan path, i would focus more on the beliefs and daily practices of that specific faith and less the spells. if you just want to cast spells, again, i would focus on things like energy work before spells.
i would start by daily meditation, charging, centering, grounding, shielding and creating psi balls, this will give you a strong foundation in 'the basics' of magick and help you when you feel ready to try your first spell.
