If you were going to modify any you should start with my Pinterest Share mod. It already shows per post.

You would need to modify the template to add the Facebook and any other share buttons you want.

Pinterest requires URL Encoded URLs so you will need to modify the plugin too, grab the per-post URL before it is encoded, and make it part of the array that is registered to the template.

Finally you would move the template hook the mod creates to a suitable location in your postbit.

Then... wallah... facebook in every post.
