To add to this. . .
I think conditioning is really important because it will allow you to recover quicker between lifting sets and allow fuller recovery between workout days. Also, a healthy body will use calories more efficiently and make your workouts more productive. You'll also have the energy to get through longer and tougher lifting sessions.
If conditioning is a priority, then lifting has to be reduced a bit; you can't serve two masters. In that case lifting 2 days and conditioning 3 days seems to be effective. Once a certain level of conditioning is achieved, then you can reduce it and maintain while adding back in a lifting day.
Seeing that you are cutting calories at the moment, your workouts won't be nearly as effective as when you are in a calorie surplus. I see this as a great time to reduce lifting days (which is still effective) and work on some general conditioning.
