I created a page called (let's say) OurGroup. The content is

Then I *think* I want to say this at the top of every page that I want to
restrict. Is it sufficient to say this at the top of each of the pages?

#acl OurGroup:read,write,revert,admin All:
  
acl processing works as (from HelpOnAccessControlLists page):
So, unless your acl_rights_before allows others, your acl will do what you want. Also, you do not need to add the "All:" part unless the acl_rights_after actually allows others.
Will this do the trick?

Also, my acl_rights_default is currently set as:

acl_rights_default = u'Known:read,write,delete,revert All:read'
  
The acl_rights_default is ignored if your page includes an acl (third point above).
Can I assume that the presumption is that what I'm describing will work
*because* FreddyFish and myself will be logged in and therefore Known?
  
Not from what I can see. The members of OurGroup have access because your acl allows it, which does not depend on acl_rights_default (which follows your acl in the processing sequence, and is ignored because you provide an acl).

Hope this helps,
