With respect to the NE context, books on the Antinomian controversy by David Hall and William K.B. Stoever deal with this in a measure (the latter writing "A Faire and Easy Way to Heaven"). More directly dealing with Preparationism is Norman Pettit's The Heart Prepared: Grace and Conversion in Puritan Spiritual Life. And with respect to JE, there is John Gerstner's Steps to Salvation.
