I want to change my PSN Name...why isn't this a option? If I do delete my current account will I still have my game saves, playstation plus, psn purchases, and (I know this is a long shot) trophies
Welcome to the PlayStation Community!
As you already know your PSN ID once created cannot be changed.
If you delete the account that has the PS Plus attached to it you will lose access to that & the others things yes, Plus is tied to the purchasing account as are trophies.
