Hello and welcome!
Home brewing is a great obsession, um, I mean hobby. A great place to start is by reading John Palmer's book "How to Brew". You can read the first addition online for free at http://www.howtobrew.com or you can pick up the latest addition from your online or local book seller of choice.
After reading the book I would recommend getting an Ale kit from your LHBS (Local Home Brew Shop) or one of the online ones.
Remember, come back here with any questions. There are a ton of knowledgeable home brewers that can help you along.
Oh yah, when you start to actually brew I have this piece of advise, RDWHAHB! (Relax, don't worry, have a home brew!) Just not too many while you're actually brewing. You are dealing with very hot liquids ;D
