If you can turn the wheel with "a small amount of effort" it might mean someone's stuck a dodgy recon on there previously that won't be up to shifting the car if you need 4WD. Mind you, if you're built like Shrek, then the result is null and void.
Whether you have Torx sockets or not, I find the best way of removing the prop is to do the lower bolts that you can get easy access to, then roll the car forward a bit so that more bolts get easy access. I either do it from my inspection pit or drive the car up onto blocks first to get better clearance underneath. Just use as many blocks as needed to roll the car.
