Well I'm not sure on a 3i but on a 4r there is a records file that contain 
all the DNS stuff for the GUI.
/etc/named/records

You can use commandline perl on this file to make all the changes you want 
(make a backup first just in case).
perl -pi -e 's/searchfor/replacewith/g' filename.htm

For instance if you want to change the TTL from 86400 to 3600 you would do 
something like this:
perl -pi -e 's/86400/3600/g' records

Then go into the GUI under the DNS settings and hit "Save Changes"

Same for all the other changes.

That should do it.
