The recovered keynote files should be placed in their original folder(s).
Data Rescue should do this automatically.
What happens when you try to launch the presentation?
Yes I am here.
Are you happy to continue now?
You will need to try repairing the recovered files.
There is one quick fix that usually works:
1: Rename the file to a .zip file - make a copy of the keynote file, and if the file name ends with .key, change it to .zip. Otherwise, just add .zip to the end of the filename.
2: Open the zip archive. Double click on it, and Finder should decompress the .zip archive into a folder of the same name. If you open the folder, you should see a bunch of files there, including any images you've added to your presentation.
3: Rename the folder back to a .key file - highlight the name of the folder, press Enter to rename it again, and change the extension at the end to .key
Now try opening the keynote file again. Let me know if that works...
To get around the error message you are getting when trying to expand the ZIP file, try using StuffIt:
