The bolts that go through the center of the mounts are the most risky. As Dan said, soak them. The unique captured nut they spin into can be damaged if the bolt is rusted to it and you try to remove it aggressively. I don't find it to be a problem very often. There is a torque spec for those bolts and it's not very much... maybe 50nm? Don't over tighten them.
Do one side at a time. Remove the calipers and tie them up so you don't stretch on the brake hoses, or disconnect the hoses and cap them. After removing the bolts for the mount on one side, the subframe will come down some but will then be limited by the engine. At this point you can undo the center bolt on the engine mount to pull the subframe down further. Its also a great time to change the engine mounts, of course. A floor jack is useful to support things and move them back into place. And make sure you're not stressing the engine fan against the shroud. You can usually pry out the mounts from the subframe with little effort. Installing the new ones is much easier with a rubber lubricant. I use the MB stuff, but I suppose you can use soap and water also. It's really not a terrible job unless there is rust. Good luck!
