I agree, terracing is the way to go. If you can make a level path from left to right, starting about half way up the steps, you'll be able to reach any section for maintenance. Some of those large rocks will be in the way though, so you'll need some help to either get them moved or removed. You might even be able to re-use them as a kind of retaining 'wall', otherwise you'll need to build one, perhaps using wooden sleepers. It'll be hard work and may need a professional to do it safely.
