I don't think you will encounter any areas with any danger. Having a rock hit you on that trail is probably about as likely as being hit by lightning -- always possible, but almost never occurs.
I saw a video some hikers took during/just after the earthquake, while on the final section between Trail Crest and the summit. They were awed by the rock fall going down a chute near Hitchcock lakes, but they didn't make any remarks about any local or nearby rocks falling.
