Regarding the apparently missing 80GB, try shutting down your Mac & restarting.
If you need to recover your deleted your iPhoto Library, I suggest trying Prosoft DataRescue3. You can download a trial version and have it scan your hard drive. Assuming it finds your deleted iPhoto Library you can purchase DataRescue and recover the library.

You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed.
