Audio/prog vs interlaced sequence for gig next weekend

Next weekend I am shooting a pageant. The PA they have only has RCA output on it. I am going to be taking my DAT recorder with me and just going to go straight into that and sync it up in FCP later. This will make the audio mostly useless on my HMC150. My question is this. I will use the camera audio a little bit in terms of helping me sync up the good audio from DAT. When I log and transfer in FCP, the audio gets converted to 48k. Should I set the DAT to record 48k as well? I am worried if I record the DAT at 44.1 I may run into some sync issues with trying to match the camera audio and DAT audio in line. So, record DAT at 48k or won't it really matter...I would think it would but not an expert.
Second question. I was planning on shooting at 1080i60. My b-roll cam is a Canon Vixia HG21 which only shoots at 1080i60, so I figured I'd just go interlaced on Panasonic as well. I don't need a film look or anything, so the video look for this live pageant is fine for me. However, now I have a friend who will be shooting with me as well. He will be roaming on stage getting shots of the girls exiting/entering etc.. He is shooting on a 7D, which to my knowledge only shoots 1080p24/30. I do not want to go the 720 route with the Panasonic or 7D. I guess what I am asking is it ok to mix progressive and interlaced video in FCP? My sequence will be Pro Res 422, upper field first, 1920x1080. I guess I am curious if anyone has mixed the two types of video together before. Maybe I should go 1080p30 on Panasonic to match the 7D and just worry about dropping the interlaced video from HG 21 into the sequence and trying that to?
Any info with regards to the audio and the video progressive/interlaced situation is appreciated.
 
Well, I think I am just going to record the audio at 48k. Seems best to me to have all audio sample rates a match. Can anyone comment on my progressive/interlaced FCP sequence question?
 
You will have to deinterlace the interlaced footage for a progressive video so you lose resolution. Best bet would be to process the ProRes footage using JES Deinterlacer to match the progressive footage.
