User files and folders

I am moving user private and public files to a new file server, and have some questions.  I've read a few threads in here and get different answers or maybe I'm not quite getting it.

The current file server is a w2k server and the shares are all screwed up, (I took over about a year ago and now it's time to fix the file server).  The new FS is WS2003 R2.  What I want is this:

1.  Each user has their own home folder (wether it's %username% in the AD profile or manually created.)
2.  Admin has full rights to the \\SERVER\Users\ folder (we get asked quite often to give rights to so and so's folder to xyz.
3. Users can see all the folders in the share but can only access their folder.
4. User can't delete his home folder, but can do whatever they want within it.
5. Need to be able to easily add permission for another user to access and modify if they are supervisor.
6. Need to be able to easily move all files out of that folder into another folder.  (User A quits,  User B is hired and needs their own folder, but will need access to User A's files.  Rather than keeping User A's folder and granting rights, I want to move them to User B.  The problem I've had before is that once moved, User B can see all the files, but doesn't have rights to them.  Then I have to change the permissions.  Well now it says I don't have rights so then I need to take ownership of the folder, etc. etc.).

I haven't mastered the  %username% option because it seems everyone still gets permission to that folder.

It seems it should be easier than this.  I appreciate any input.
