If you want to get the most out lifting, do not mix it with cardio. Do cardio in the morning and lift in the evening. Even better, do your cardio on the days that you don't lift.
When you lift, you want all the energy that you can possibly get if you want to build the most muscle in the least amount of time. There is no way that I can squat the same weight after cardio that I can squat before cardio, when I'm fresh and full of energy.
If you do cardio right after lifting, you are interrupting the muscle recovery and growth that you just triggered through lifting. After lifting, you should have a post workout meal and relax for the rest of the day.
If you want to burn a lot of fat, get your priorities straight: Diet first, then lifting, then cardio. Lose the fat slowly, no more than one pound a week over a long period of time. This way you'll look much better and you won't regain all the fat after a while.
