A turnover from picture to sound is a pretty complicated process and a lot of things can go wrong, especially with Premiere. As for the video, the best codec for you to get from Premiere will probably be ProRes 422 LT. They'll need to do an AAF export for the timeline audio but there are a lot of ways that can go wrong too. Make sure there's a timecode burn-in on the video and that the frame rate of it is the same as the actual video's frame rate. First frame of action should be at 1 hour 8 seconds, with a single frame pop of -20dB tone at 1 hour 6 seconds with a visual cue frame to match with it. Video should start at 1 hour. Get them to provide an audio guide track along with the video, dialog panned hard left, music and effects hard right. Said audio can be embedded in the video or not, either way is fine. When you import the AAF tracks into Pro Tools, check their sync against the guide track. Sometimes fades and crossfades in the AAF can mess up sync, so if it's out of sync, they may need to make you a version of the AAF without the fades. Make sure your Pro Tools session setup is set to the frame rate of the film, which should be 23.98 or 24. Your video track will show the frame rate number in dark red if there is a discrepancy here.
