No offense taken.
Was just mis-lead by the title you assumed.

Evidently you still have access to the file system of your Kindle (since you plan to replace files in it) -
Have you created an md5sum listing of the existing files on your device yet?
Where did you post that listing?
Note:
You only need listings of those portions of the directory tree you think you might have changed.
But of course, it will probably save time in the long run if you just copy off the entire file-system tree of the Kindle into a directory on your PC (better and faster tools available there).
Also: There is a tool which will probably help you in creating that list.
