Also, request access to the wardrobe head of department and art department so the recordist can lay down some rules.
This is the same as the DOP saying to wardrobe: No high contrast stripes on actors - this will not work with well with many HD digital cameras.
The head of sound department will say things like, no dangling metallic jewellery, no noisy materials etc.
No noisy fans used as set dressing etc.
Also having location sound in mind when choosing locations. I hhave never had a location scout or director choose a location that is good for recording. They always go for the visuals! Fair enough, but then one must allow time for retakes and wilds and crew silence for recording some extra ambient backing for the recording mix in post. Allow time for waiting for for planes or traffic or car alarms or trains or rain or wind or birds etc in the schedule.
That's what comes to mind that has not already been said by the great answers above.
