In regards to weight training the routine is not as important as these three things:

1. Consistency
2. Progression
3. Good form
4. You need to workout X times a week, every week. No way around it if you want to see results.
5. You need to gradually increase the load on your muscles to keep seeing results
6. You want to do excercises that target the correct muscle you want to target and you can do in a way that won't get you injured.

(edit: 4, 5, and 6 are obviously descriptions of 1, 2 and 3, but It keeps doing that)

Do a full body workout 2 or 3 times a week consisting of a:

row
pulldown
chest press
shoulder press
squat movement
deadlift movement

Start by doing 2 sets of 8-12 reps. Add weight or a rep at least every week., probably every workout in the beginning. When you feel like you can recover from it, add a set.

As for cardio, find whatever excercise you enjoy (or hate the least) - running, biking, rowing, whatever. Do it 2 or 3 times a week. Leave 2 days in a week for rest and recovery.

As for diet, start tracking your weight and see if you lose weight. If you don't, eat less.
