Websites and online lessons can be a stinking awesome way to teach yourself, and some of the tab websites are really helpful for figuring things out - ultimateguitar.com is a good one -, but if you're really interested in improving your playing, a real live guitar teacher is the place to go. Most music stores, and even a few chains - such as Kennelly Keys or Mills Music - offer lessons and often have amazing teachers. From my own experience, you're going to have much better odds at finding a good teacher at these places than a bad one. Just go down and ask around. The best part about it is if you ever get the the point where they can't teach you any more, they'll give you a number of a guy who's better than them!

The thing with playing guitar is that no matter how good your gear or teacher is, you don't get better without practice - with a metronome - everyday. Steve Vai used to play for ten hours a day. When you play that much your fingers may start to bleed, which'll leave really cool blood stains on your guitar. You get better, and your guitar looks better - win/win situation. Hope this helps.
