This document [removed] gives a rough idea how the boot process works for the internal SD. A.k.a. the way to a more-than-reset recovery.
I myself have never used Clockwork Recovery, do I don't know anything. I however believe it would be easier just to do the modifications the apk does directly to the SD.
