Losing weight for skiing

Hey fellas, I am a little bit of a chunky monkey and I am trying toslim down for the rest of this year and next year's ski season. I am 6 ft 200 lbs with only a tiny bit of muscle. I was planning to change my eating habbits and start hitting the iron palace some more but I was wondering what I should specifically work on. As of right now I was thinking doing lots of legs, core, and cardio. Any thoughts?
