  On the containing folder:

P1. Block inheritance (uncheck "Inherit from parent")
P2. Remove all directly applied permissions (start with an empty ACL)
P3. Grant "Read & Execute" on "This folder, subfolders, and files" to staff
P4. Grant "Read & Execute" on "This folder, subfolders, and files"  to
whoever else needs it
P5. Grant "Create Files / Write Data" on "This folder only" to staff
P6. Grant "Write" on "Subfolders and files" to staff

Read & Execute = Traverse / Execute; List / Read Data; Read Attribs;
Read Ext Attribs; Read Perms

Write = Create Files / Write Data; Create Folders / Append Data; Write
Attribs; Write Ext Attribs

  Notes:

N1. "Delete" access is needed to rename files.  No delete means no rename.
N2. Some programs (such as MS Word and MS Access) expect to be able to
delete files in the directory containing a file they can write to, and
may malfunction in this scenario.
N3. The ability to change existing contents of files means the user
can still erase all data from the file and save that in place, which
may be the same as "Delete" for practical purposes.

  Avoid explict "Deny" permissions if at all possible.  You're much
better off blocking inheritance and then building up a set of granted
permissions.
