I'm just upgrading from iPhoto 8 to 11.
Once the upgrade of the database was run I'd lost a stack of thumbnails. So I found the apple advice on rebuilding with the menu that comes up on opening with cmd+opt held down. But then I get alert after alert about not being able to open photos because the originals can't be found. I thought the point of iphoto was you never get to see the files to navigate to and molest. So...I can't see them to navigate to. In any case, there seem to be lots of them (I managed to hit stop quick enough after about 100 attempts). Do I have a very long night ahead or is there a standard fix for this?

That message turns up when you have a Referenced Library but this
When I used Spotlight to look up the filename and then 'reveal in finder' it was jumping to 'Masters'.
is a Managed Library, so I can only guess that iPhoto is more than somewhat confused.
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .
