You could and should spend a lot of time getting rid of Alchemilla mollis - it's an absolute b****r. Don't worry about losing it; there will always be some left if you want a bit to keep in a zoo. The rest looks like a fabulous adventure. You will be able to strim back a lot of what appears to be rough grass just to tidy it, but don't go too far in just in case there's something interesting hiding there.
Depending on how much help you have, try to identify things that must be done and do them and then pick a couple of small areas to clear and work outwards from (probably near the house). Be aware that there may be lots of bulbs, as well as other plants that die away to nothing.
Good example of what a Christmas Tree can turn into after 30 years!
