60 min for a workout is plenty of time if you train efficiently. I set my limit in the gym at an hour and 15 minutes and am usually out within 1-1hour and 5. Cut your rest periods down to 30 seconds max, 15-20 if you can handle it on a particular set.
Classic split is Mon:Chest/Tris, Wed:Back/Bis,Fri:Legs.
Some things I've discovered through experimentation that may help you out:
1)I would not focus on a few power movements, for strength or looks. Hitting a bunch of angles really helps development and also helps strength (for me, this was particularly true with back.)
2)I have found it beneficial to pre-exhaust with isolation movements and then do compound movements, even though conventional wisdom says to do otherwise.
3) For a really efficient workout, Superset compound with isolation movement. When doing this workout, I stick with compound movement first, isolation movement second.
