getting my note 3 tomorrow should I do a master reset before I set it up and installation apps

If it's new, I don't see why. But it wouldn't hurt if it gives you piece of mind.
 
There's no need to do it on a brand new phone.
I would recommend doing it after major updates though. Either that or wiping the cache partition occasionally
