This is a superb combination for HQ interview sound. (I'm actually an audio guy first...)
Using the Tascam to record audio you can either attach it to your subject or run the lavalier to them from a distance using an XLR cable. Mount the shotgun for added depth or mount and direct it towards the interviewer.
