No, you are at the right section.
The last move should always be Calm Mind or Shadow Ball, depending on the Delphox you want.
Cam Mind Delphox
Like the title implies it, Calm Mind Delphox will usually use Calm Mind six times, then proceed to sweep.
EVs: 252 HP / 252 Speed / 4 Def.
ScarFox / SpecsFox
ScarFox is better because Delphox already have an excellent special attack, thus you will have to work on the Speed. SpecsFox can be used with Sticky Web support very effectively, though.
EVs: 252 Sp.Atk / 252 Speed / 4 Sp.Def
The only one I can think of is Magician Fire Gem, to steal an item. Here again the EVs remain the same as for SpecsFox / ScarFox.
As to properly answer, max out the speed (252 Speed / 252 SAtk) and 4 Sp.Def as well, or stop using Delphox, as Mega-Houndoom and Alakazam outclasses it as Fire and Psychic special sweepers, respectively. More informations can be found on theses three pages.
I hope this helps.
