Pretty neat watch list there . While perhaps not essential to the Mandoverse , I would add the Landing at point rain episodes as well as the Pong Krell arc . I haven’t rewatched the series in many years now , but when I think back to the series ,those two stories are the ones that really stuck with me as they dealt with important themes and had much drama and action . I would probably add in most of season 6 " the lost missions " as they are also important to the overall lore of the saga as a whole ,explaining the mystery of Sifo Diyas , Yoda’s first visit to Dagobah , communing with Qui Gon etc . Those are episodes I wouldn’t want to miss .
