How might one make all creatures become level 80?

And if possible, can it be done to a certain zone, for example making all creatures in Naxx level 80

Not sure about the zone, but to make ALL creatures level 80, run this SQL (this will ONLY change their level, not their health etc)

UPDATE creature_proto SET minlevel = '80', maxlevel = '80';

To make it for just naxx, I would recomend to use this SQL with this link. Find the creature entry and put it where it stands xxx to make him into 70

UPDATE creature_proto SET minlevel = '80', maxlevel = '80' WHERE entry = 'xxx';
