If you are new, I would suggest looking into the basics. These include, meditation, visualization, grounding, centering, energy flow/control, etc. I believe that there is a page in the featured articles section that covers all of these, if you wish to look into it further.
You don't necessarily need supplies. Tools are simply there to help us focus and better direct our energy toward our desired goal. If you have a strong enough belief in yourself, a strong enough focus on your goal, and you put enough energy into your magic workings you should be fine. Also, keep in mind that if you can't do it without magic (change your genetics for example) then you can't do it with magic either.
I've personally found that protection spells, candle spells in general, and knot magic (if you are unable to acquire candles) are quite easy to learn and cast if you are new.
