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

Issue Summary

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.
