When I managed a similar situation, here were the bare-bones questions we emailed them before tech. Maybe some of them would help?
List any set pieces/props that will be set onstage during the transition into your show.
List any set pieces/props that will be brought onstage during your show.
How many sound cues are you planning to have?
Any any actors entering from the house?
Will you be needing any crew assistance (scene changes, prop handoffs, costume changes)?
We also timed each piece during tech and noted that.
