There is all kinds of information out there - plus, most (probably all) recipes for 5 gallons can be scaled down to 1 gallon. I've brewed everything from Kentucky Common to Oatmeal Raisin Cookie Stout, and have had a great time doing it. I am by no means an expert, but I am loving it.
As a suggestion, I'd recommend these three books, which are geared toward small-batch brewing and present a couple of different ways to go about it. The first two, from Brooklyn Brew Shop, have a myriad of great recipes and tips that are tailor-made for the small-batch brewer; they also write in a way that is very encouraging and inspiring, which is worth a lot in my book:

They are a bit pricey at BBS's website (
www.brooklynbrewshop.com), but can be found for pennies at Amazon.
The second book is really awesome, as it comes at small-batch brewing from a different approach; in a lot of ways, it expands on what BBS will teach you, and allows you to break down the brewing process and learn to brew a few basic styles of beer (Pale Ale, Brown Ale, Hefeweizen, Stout, Porter, Saison, Barleywine, Scottish Ale, Abbey Ale and Pilsner):

I really can't recommend any book over the others, and believe that you would be pretty happy if you got all three of them.
Hope this helps -
