The formatting for the chapter headings was produced using the titlesec and TikZ packages.
The partial ToCs (with the decorative rules) were obtained using the titletoc package. Simply calling \DoPToC after \chapter{...} produces the partial ToC and its rules.
The epigraph package was used for the epigraphs.
\ttl@printlist(fromtitletoc). The patching was done using\xpatchcmdfrom thexpatchpackage. – Gonzalo Medina Jul 06 '13 at 16:32
