If you've had 3 consecutive, identical gravity readings, then you can presume its finished.
Stabilise it, with sulphite (campden tablets) and sorbate. You can just rack onto them.
If you want to use honey for back sweetening, I usually do that at this stage, with a 50/50 water honey mix. Why now ? Because honey can cause a haze (protein I think it is), so I only need to clear it once.......
I use the syrup mix incrementally, taking a reading after each addition is mixed in and I aim for 1.010-1.015 as that's where I usually like my.meads.
Then I clear it....
