Best way to get rid of extra fat

[ricardo222222]

So I've gone like 3 months now with a good 3000+ calorie diet and lifting 4 times a week to gain muscle mass. I put up 5 kg (from 65kg to about 70kg). I'm 18 and 174cm tall, so I have a long way to go to get where I want in terms of muscle. But now I feel I have some extra fat that I want to get rid of before going on with bulking. So I ask here for your help. Is it fine to go from 3000+ calories to 2000 with the same percentage of protein, carbs and fat? More or less? And what happens with lifting? What would be a good routine for when I'm cutting? Right now I go 4 times a week and do arms and chest on 2 days and legs, back, and abs on the other 2 days. 3 different exercises for each part, 4 sets of about 8 reps. So now I suppose I have to stop doing that much but still do some, and what about cardio? Like how many times a week should I be doing it and which exact exercise? I would like suggestions for cardio in the gym and at home, as I can only go twice per week now to the gym, so the rest I would do at home. I think that's about all the questions I have, thanks for answering.
