Here's a suggestion, only a suggestion. If you like what you've got going, then by all means stick to it.
Sun: Deadlifts, Bent-Over Row, T-Bar, Lat Pulldown, Shrugs, Preacher
Tue: Bench, DB Military, Dips, Heavy Abs
Thur: Squats, Stiff-Leg Deads, Bio Ball Raises, Calves
This would get you working similar groups on the same days without so much cross over from one day to the next, and give your legs two days of rest before training back. Back will be your heaviest day, but it's followed by a lighter day of chest and shoulders. This split may give you more nervous system recovery.
