Have you checked the FAQ page?
probably, have looked around at most of the link on HawkEye plugin side.

Also cant rollback some stuff that burned up with fire.

I have also noticed this. I had a griefer who burned down an entire forest and when I rolled it back it left the forest extremely patchy. Bits and pieces of logs and leaves everywhere. He also placed lava and although it got rid of the source block, it left the streams of lava, so I had to restore my entire map from a backup to get rid of the damage.
