Diet should be your top priority. In general, take out about 500 calories a day (perhaps 2000 cals a day) and eat 5 meals a day, each spaced out approximately 3 hours apart. If you don't have time to do that, 3 meals a day with two small healthy snacks in between. Balance your meals to get about 35% protein, 35% carbs, and 30% fat. Keep in mind, those numbers aren't set in stone. For a basic guideline, check this out:
Do plenty of cardio.
Even though you aren't aiming to build muscle, you should definitely incorporate weight lifting. Keep in mind, each pound of muscle gained burns an extra 50 calories a day. If you build some muscle first, cutting will be accelerated. And you'll look much better.
That's just a basic guideline. Just think diet first, then cardio and weights.
PS. Looking over your stats, I would build muscle first. However, that's just a suggestion and I'm just offering an answer to your question.
