You'll learn to reach over your head while lying on your back to keep from being drenched in oil.
You still have the risk of getting splashed if standing. Get a large, low-profile plastic tub/tote to catch the mess when you separate the sump plate.
As others have said, the Quick Jack will give you plenty of room if you're comfortable working on your back. An air or electric impact will reduce the amount of over-the-head reach time for removing the screws.
Oh, and for those who use concrete/cinder blocks as supports, they need to be oriented such that the casting holes are vertical, not horizontal.
