For starters you say 24. Is it 24.000 or 23.976? Not that it matters, but you want to keep frame rates consistent from shoot, to transcode, to Avid project type and 24 and 23.976 are not the same thing.
Assuming all that is correct, I never import the ALE for relinking. Some have success with it, but I find they can unlink over time for no reason whatsoever.
Once you copy files to MXF/1 folder, drag and drop all the AAF files into your bin (or import). Those will relink automatically. If you want to have the additional metadata from the ALE, select all the master clips created by the AAf files and merge the ALE into them.
