Ok, so I need help figuring out this one last piece, and then I will have a workable, functioning permissions scheme.  Here is what I have set up:

Plugins:

• Role Scoper
• Revisionary
• User Role Editor

Using URE, I created a custom role (which my test user is a member of) with the following caps:

• delete_pages
• delete_private_pages
• delete_published_pages
• edit_others_pages
• edit_own_pages
• edit_pages
• edit_private_pages
• edit_published_pages
• publish_pages
• read
• read_private_pages

Then I have a role group, "Test", of which my test user is also a member.

I then placed a Page Revisor restriction on all pages.

Finally, on the pages that I want my user to have access to, I granted "Page Revisor" to the test group, and had it propogate down to the sub pages.

This meets the following of my requirements:

1. Users can edit pages to which they are assigned
2. Users are forced to submit revisions for published and new pages for approval
3. Users can upload media
4. Users can choose templates on new pages
5. Users can choose page parent on new pages
6. Preview Changes
7. Save Drafts

This is by far the most workable solution I have found thus far.  There is one minor hitch that is causing me frustration.  It is related to items 4 and 5 above: Users can access the page attributes on NEW items, but on published items, it's a no go.  The page attributes box dissapears for them entirely. Any help would be GREATLY appreciated.
