You could use POSIX ACLs for this, or make the files group writeable and 
add the user you want editing the files to that group. Since the 
processes run as root, I'm not sure there's much point to this though.

www-data if for web  stuff; not sure why one would use that. Going the 
non-root route would typically result in a samba user being created for 
this purpose.

The fact that the files are owned by root indicates you didn't create 
them as a domain user. Only domain users are governed by the edicts of 
smb.conf; root is an anarchist.
