Unless you're an absolute beginner, in which case doing about anything will help, it is difficult to build significant lean muscle mass and at the same time lose fat. This is why traditionally bodybuilders would bulk and then cut. Leangains is a protocol that builds muscle, albeit at a bit slower rate, and minimizes fat gain - or protects muscle mass while you're cutting. Google for more info if you're interested.
If you're not too torqued up about it and just want to get into better shape generally then just get into the gym, hire a trainer for a couple of sessions (or maybe your gym will give you some beginner lessons free) to show you what to do then go for it. Some strength training, some cardio.
