If you're relatively new to Wicca/Witchcraft, Peridot, I'd advise that you don't get into Crowley for a while yet. Good Ol' Uncle Al had a wicked, deadpan sense of humour and much of what he wrote needs careful interpretation; he was fond of winding up the Puritans - and the press! There's much wisdom in his writings but it needs to be approached with caution. He himself wasn't Wiccan, but much of Wicca as it comes down to us via Gerald Gardner was heavily influenced by Crowley's work.
Buckland and Cunningham are good authors to begin with; depending on where you want to go after that, there's the Farrars' "Witches' Bible" (traditionalist), Huson's "Mastering Witchcraft" (for the practical craft without the religion), several books by Starhawk (feminist and environmentalist), etc., etc. There's also Gardner himself, with "Witchcraft Today" (which, despite its title, is mostly historical) and "The Meaning of Witchcraft." That lot should keep you going for a while.
Oscar Wilde was a Wild guy, to be sure; but, again, lots of earthy wisdom in his writings.
