These two threads are great for deleted scenes and storyboards for Return Of The Jedi, they do focus more on the space battles, but there is some also stuff on rebel soldiers in the Falcon from deleted scenes.
There may be something in there about the battle footage for the Forest on Endor scenes in the links or storyboards?:

Like Juno, I thought we’d one day see more added footage with the Ewoks, Rebels and troopers in one of the Special Editions too.
