Good luck, you've got a lot of work to do. I've restored a lot of photos for my mother and know that you will get to be very well acquainted with your clone tool/brush. As Dani said, go easy on the dust removal, despeckle as it will make you photo look like plastic if over-done. I found myself cloning and cloning and cloning even tiny little places to get rid of dust. Just be patient and save often.
