A few questions on different subjects

So. I've been playing for a month or two now actively and built a claim a while ago, but I was curious if it was possible to move your claim stone without rendering your property worthless? I don't want to destroy the claim without knowing since I have currently 1600 area. I want to move the claim so I can place a larger house near it's location.
I was also curious as to how the new worms work. We figured out that we can replace worms into the compost bins and such, but how do we make them eat plants to take on their alchemic properties?
And, now that I've become a rather successful blacksmith, I was curious how to use the stalls in Boston? Not the NPC ones, but the player ones. I don't understand how they work and have tried to place objects into them to sell them.
-Thanks.
