I don't know if this helps, but generally I keep my music in FLAC. I convert a lossless PCM (.wav) copy for use in the NLE, and on export of the final video I choose uncompressed PCM matching the source format (I.E. if my source is 16 bit 44.1khz, that is what I use). This will guarantee as little loss as possible when the time comes to do the final encode, regardless of which format I choose (AAC, MP3, etc.)
Taking things a step further, I generally encode x264/FLAC/MKV. This means that after I have encoded the video, I simply mux the original lossless FLAC audio file with the video using MKVMerge. These days, the difference in filesize between lossy and lossless for this purpose (AMVs) is negligible in most cases.
