merry meet ^_^ what exactly are you studying?
might help you learn the basics. from there, there's books and articles that can help you on your path.
you don't really need to buy anyting just yet. would be cool to have an athame, wand, cauldron, and all the other tools, but to start, you just need a book of shadows. it can be digital or a notebook. it doesn't have to be lined, just find a book you like and use it. your book of shadows is the most important tool, and you should like the notebook you're using, that's really it. it doesn't have to be leather, or have a pentagram on the cover. find a notebook you like and use it. you can also decorate it however you want.
how to do a spell, i'd stay away from spells for a little while. it's common to do a year and a day ceremony where you study. spellcasting usually isn't done for a month or so, until you get circle casting, colour association, moon phases, meditation, charging/grounding energy and whatnot down-pat. when you feel ready to actually cast spells, start with low magick, a simple candle spell would do. see, magic(k) is energy found in nature, a spell won't work if you can't charge and focus this energy. [there are other factors, but the energy is the key]
if you feel alone, join a coven, there's a bunch on SoM [spellsofmagic] you could use. read their description and choose one that feels right for you.
