The oil pan shouldn't be catching on the subframe. Did you disconnect the ground cables? One on each side of the engine, Passenger side bolted into one of the motor mount bolts, the driver side... I can't remember, but I want to say another motor mount bolt. You'll need to slide the engine forward a tad bit to clear the torque converter to flexplate nipple. Then it should come straight up.
You'll also have the power cable going to the starter (running in front of the engine) that is bolted down to the k member in the front under the engine, and to the side of the engine on the pass side.
As far as the engine and tranny coming out together, it's theoretically doable, but it's a lot easier to undo the bellhousing bolts... al least in my opinion.
