Restricting nodes that can be added by workflow state and manipulating quees access

I'm using nodequeue in conjunction with workflow, views, and panels to create an editorial workflow, and I have a couple questions:

1. I want to limit the editors ability to add nodes to a queue based on the workflow state. For example, I have a wf with 3 states (Draft, Review, and Published), and I want to allow editors to only add nodes to a queue if the node is in the Published state. Is there a way to restrict that with nodequeue? Or do I just need to add a filter to my view that only displays nodes in the Published state?
2. How can I give my editors access to manipulate the position of nodes in the queues without giving them access to the admin area? I can see the "manipulate queues" and "manipulate all queues" permissions, but I don't see any new menu items or locations for doing without access to the admin menus.

Thanks.
