I, being Hemophobic, am opposed to using blood in the Craft to begin with. As for Candles, they can help direct energy and focus better (a very good thing, I might add). As for summoning things, I'd advise you to stay clear of summoning things until you're more experienced.
i suggest reading up on the basics and practicing meditation, chakra work, possibly lighter forms of Divination for now. Don't put a lot of emphasis on Spellcraft - it's such a small portion of true Witchcraft. The Craft isn't all about casting spells. And one must understand what they're doing before they do it. It's easier to not get burned that way.
