references and article structure
Fornara 95  contains all the relevant ancient sources on this topic.  For discussion see Meiggs' chapter on this topic in Athenian Empire (1972) as well as Badian From Plataea to Potidaea (1993) chapter 1.  This article should be aware that there is  no scholarly consensus on this topic.  No peaces, one peace or two peaces are all arguable stances to have.  The article should give reference to the main primary evidence and outline possible solutions.  Since there is no agreement on whether there was a peace, the 'effects of the peace' content (towards the end of the current text) should be presented rather as 'developments a peace with Persia could be used to explain'.
