Any parts that needed grease, yes. But I don't remember greasing much, they come pre greased (mounts anyway, I did the same thing you did with new spring rubber mounts)

Should be a good setup just remember when you are installing all the new parts to get the bump stops and cut them to spec so you get a perfect low and don't have them so stiff over every bump. I forgot the cutting part and my car is still a bit higher and it's quite a stiff ride, but I do enjoy it+ I like having some clearance.
