1:34 - Katooni (after Ganodi doesn't answer on the comlink): "Where could she be?" Luke has a similar line in A New Hope as he's trying to raise C-3PO on his comlink: "Where could he be?" [1:22:12 and 1:23:19], and C-3PO himself has a similar line a bit later in A New Hope: "Where could they be?" [1:29:33].
6:29 - Grievous (to Hondo): "You can dispense with the pleasantries, pirate." Vader says almost the same thing (to Moff Jerjerrod) in Return of the Jedi: "You may dispense with the pleasantries, commander" [3:58].
9:32 - Battle droid (to R2-D2, who's creating a diversion): "You just watch yourself." In A New Hope, Doctor Evazan says this to Luke in the cantina [46:40].
11:08 - Huyang: "I have instructed younglings for over a thousand generations, and these are among the best I have ever seen." Obi-Wan uses this same phrase in A New Hope when he tells Luke, "For over a thousand generations, the Jedi Knights were the guardians of peace and justice in the old Republic" [33:54].
