You should brew what you like to drink. Start with a visit to a quality home brew shop, local or online. Northern Brewer and Morebeer have starter kits available. Also, consider a good book, like "How to Brew" which you can purchase or read chapter by chapter online.
The key is sanitation. The rest is as easy as baking a cake. Get a kit, follow the direction, enjoy drinking. Don't get fancy to start, just practice with some kits until you understand the cause and effect.
