The @s mean that these files have extended attributes, that you may  
inspect by
     ls -l@ *
in Terminal.

The +s indicate the presence of extended security information, most  
likely ACLs that were added by using the Finder, or alternately,  
Terminal-fu.

Do you have children?
Perhaps someone opened "Get Info" for a certain folder, changed the  
permissions for "everyone" and then clicked on the gear at the bottom  
of the window, and then selected "Apply to enclosed items".
I would suggest that you go to the containing folder, open "Get Info"- 
 >"Sharing and Permissions", find the "everyone" item that has  
personalized permissions, and then click the "-" at the bottom of the  
window.
