How to assign permissions to choice values when using content types in a library

Question

Hi,
I just now started using content types in document libraries instead of folder structure.  The structure I was given is as follows:
Master group (library name)
L.A.
  South Street
       Number 1
       Number 2
  North Street
       Number 1
       Number 2
Boston
  West Street
       Number 1
       Number 2
East street
       Number 1
       Number 2
India
  North Street
       Number 1
       Number 2
  West Street
       Number 1
       Number 2
So, I created a Content Type called Areas (which included LA, Boston, and India) and I created choice field values for each columns (South street and North street).  Then, I gave the choice values as Number 1 and Number 2.
Now, the complexity was in terms of permission levels, wherein the client was accustomed to using folder structure.  And hence, they had given a set to users to have access only to Number 1 of West street of Boston.  Now that I have the content
type structure in place, how do I configure the granular permission for the 3rd level of the hierarchy?

Thanks for your post. I had already done this via Windows Explorer, and it works for all of the My Docs files
but not Acrobat files, which still come up in List View. I am running Windows XP still, is that a factor?
