couple of problems

I’m making a fairly advanced first person shooter and i’ve come across a couple of problems.

1: I have extra actions on the weapons that i dont want any more. i want to remove them but dont know how since they all have false owners.

2: on an action i have names of limbs which are no longer in the armature so i dont want the name to show up in the action any more, can these be deleted?

3: how do i link an object from one scene to a different scene without creating a new scene?

thanks

Andrew
