Dave Carpenter (editor-in-chief for Zymurgy) authored a great book, Lager, that I highly recommend.
Once I had the proper equipment to brew lagers, it became, and has remained, my primary focus. At this point I brew lagers almost exclusively, with the occasional ale brewed here and there.
If you like hop focused beers, German Pilsner, Bohemian Pilsner, or the newer Hoppy American Pilsner in the style of Firestone Walker's Pivo Pils, or Russian River's STS Pils, might be right up your alley.
Regardless, welcome to the joys of Lager brewing!
