You can use something like 

find . -type d ! -perm 777 -print0 | xargs -0 chmod 777 
find . -type f ! -perm 666 -print0 | xargs -0 chmod 777 

and only change necessary permissions. Probably needs GNU findutils

AFAIK GNUtar uses ctime, because ctime is the only timestamp
which cannot be set backwards.
