Aside from the tutorials that ChaseInfinity and Naitre posted, one very important thing about competitive battling is dedication. You have to be willing to do work and be able to take losing without getting angry about it and beating yourself up. Also try to familiarize yourself with the base stats and movepools of each Pokemon. Just reading Smogon won't do you much good because there are a lot of hidden gems that aren't necessarily common so when you see that Rage Sharpedo, don't laugh because it's just another strategy (oh yes, don't ever use rage Sharpedo despite what @"Squeab" told you)
